Pull staging driver updates from Greg KH: "Here is the big set of staging driver patches for 6.0-rc1. Another round where we removed more lines of code than added, always a nice progression. Some of that came from the movement of the vme code back into staging, and removal of some other of the vme driver code as there are no known users and it is very obsolete and unmaintained. It can be added back easily if someone offers to maintain it. Other than that this merge has lots of little things: - huge cleanups for r8188eu driver - minor cleanups for other wifi drivers - tiny loop fixes for greybus code - other small coding style fixes All of these have been in linux-next for a while with no reported issues" * tag 'staging-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (191 commits) staging: r8188eu: fix potential uninitialised variable use in rtw_pwrctrl.c staging: r8188eu: remove initializer from ret in rtw_pwr_wakeup staging: vt6655: Convert macro vt6655_mac_clear_stck_ds to function staging: vt6655: Rename MACvClearStckDS staging: fbtft: core: set smem_len before fb_deferred_io_init call staging: r8188eu: convert rtw_pwr_wakeup to correct error code semantics staging: r8188eu: make dump_chip_info() static staging: r8188eu: remove DoReserved prototype staging: r8188eu: remove OnAtim prototype staging: r8188eu: remove SetHwReg8188EU() staging: r8188eu: make update_TSF() and correct_TSF() static staging: r8188eu: remove unused parameter from update_TSF() staging: r8188eu: remove unused parameter from correct_TSF() staging: r8188eu: remove HW_VAR_SET_OPMODE from SetHwReg8188EU() staging: pi433: remove duplicated comments staging: qlge: refine variable name staging: vt6655: Convert macro vt6655_mac_word_reg_bits_off to function staging: vt6655: Convert macro vt6655_mac_reg_bits_off to function staging: vt6655: Convert macro vt6655_mac_word_reg_bits_on to function staging: vt6655: Convert macro vt6655_mac_reg_bits_on to function ...

The priv_dev assignment was moved below the if statement to avoid potentially dereferencing ep before it was checked but priv_dev is used in the dev_dbg() call. To fix this, move the priv_dev and comp_desc assignments back to their original spot and hoist the ep check above those assignments with a call to pr_debug() instead of dev_dbg().

When this file was split in commit 5d945cbc ("drm/amd/display: Create a file dedicated to planes") this chunk seemed to get dropped. Linus noticed on this rx580 and I've reproduced on FIJI which makes sense as these are pre-modifier GPUs. With this applied, I get gdm back.

Pull iomap updates from Darrick Wong: "The most notable change in this first batch is that we no longer schedule pages beyond i_size for writeback, preferring instead to let truncate deal with those pages. Next week, there may be a second pull request to remove iomap_writepage from the other two filesystems (gfs2/zonefs) that use iomap for buffered IO. This follows in the same vein as the recent removal of writepage from XFS, since it hasn't been triggered in a few years; it does nothing during direct reclaim; and as far as the people who examined the patchset can tell, it's moving the codebase in the right direction. However, as it was a late addition to for-next, I'm holding off on that section for another week of testing to see if anyone can come up with a solid reason for holding off in the meantime. Summary: - Skip writeback for pages that are completely beyond EOF - Minor code cleanups" * tag 'iomap-5.20-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: dax: set did_zero to true when zeroing successfully iomap: set did_zero to true when zeroing successfully iomap: skip pages past eof in iomap_do_writepage()

Pull btrfs updates from David Sterba: "This brings some long awaited changes, the send protocol bump, otherwise lots of small improvements and fixes. The main core part is reworking bio handling, cleaning up the submission and endio and improving error handling. There are some changes outside of btrfs adding helpers or updating API, listed at the end of the changelog. Features: - sysfs: - export chunk size, in debug mode add tunable for setting its size - show zoned among features (was only in debug mode) - show commit stats (number, last/max/total duration) - send protocol updated to 2 - new commands: - ability write larger data chunks than 64K - send raw compressed extents (uses the encoded data ioctls), ie. no decompression on send side, no compression needed on receive side if supported - send 'otime' (inode creation time) among other timestamps - send file attributes (a.k.a file flags and xflags) - this is first version bump, backward compatibility on send and receive side is provided - there are still some known and wanted commands that will be implemented in the near future, another version bump will be needed, however we want to minimize that to avoid causing usability issues - print checksum type and implementation at mount time - don't print some messages at mount (mentioned as people asked about it), we want to print messages namely for new features so let's make some space for that - big metadata - this has been supported for a long time and is not a feature that's worth mentioning - skinny metadata - same reason, set by default by mkfs Performance improvements: - reduced amount of reserved metadata for delayed items - when inserted items can be batched into one leaf - when deleting batched directory index items - when deleting delayed items used for deletion - overall improved count of files/sec, decreased subvolume lock contention - metadata item access bounds checker micro-optimized, with a few percent of improved runtime for metadata-heavy operations - increase direct io limit for read to 256 sectors, improved throughput by 3x on sample workload Notable fixes: - raid56 - reduce parity writes, skip sectors of stripe when there are no data updates - restore reading from on-disk data instead of using stripe cache, this reduces chances to damage correct data due to RMW cycle - refuse to replay log with unknown incompat read-only feature bit set - zoned - fix page locking when COW fails in the middle of allocation - improved tracking of active zones, ZNS drives may limit the number and there are ENOSPC errors due to that limit and not actual lack of space - adjust maximum extent size for zone append so it does not cause late ENOSPC due to underreservation - mirror reading error messages show the mirror number - don't fallback to buffered IO for NOWAIT direct IO writes, we don't have the NOWAIT semantics for buffered io yet - send, fix sending link commands for existing file paths when there are deleted and created hardlinks for same files - repair all mirrors for profiles with more than 1 copy (raid1c34) - fix repair of compressed extents, unify where error detection and repair happen Core changes: - bio completion cleanups - don't double defer compression bios - simplify endio workqueues - add more data to btrfs_bio to avoid allocation for read requests - rework bio error handling so it's same what block layer does, the submission works and errors are consumed in endio - when asynchronous bio offload fails fall back to synchronous checksum calculation to avoid errors under writeback or memory pressure - new trace points - raid56 events - ordered extent operations - super block log_root_transid deprecated (never used) - mixed_backref and big_metadata sysfs feature files removed, they've been default for sufficiently long time, there are no known users and mixed_backref could be confused with mixed_groups Non-btrfs changes, API updates: - minor highmem API update to cover const arguments - switch all kmap/kmap_atomic to kmap_local - remove redundant flush_dcache_page() - address_space_operations::writepage callback removed - add bdev_max_segments() helper" * tag 'for-5.20-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (163 commits) btrfs: don't call btrfs_page_set_checked in finish_compressed_bio_read btrfs: fix repair of compressed extents btrfs: remove the start argument to check_data_csum and export btrfs: pass a btrfs_bio to btrfs_repair_one_sector btrfs: simplify the pending I/O counting in struct compressed_bio btrfs: repair all known bad mirrors btrfs: merge btrfs_dev_stat_print_on_error with its only caller btrfs: join running log transaction when logging new name btrfs: simplify error handling in btrfs_lookup_dentry btrfs: send: always use the rbtree based inode ref management infrastructure btrfs: send: fix sending link commands for existing file paths btrfs: send: introduce recorded_ref_alloc and recorded_ref_free btrfs: zoned: wait until zone is finished when allocation didn't progress btrfs: zoned: write out partially allocated region btrfs: zoned: activate necessary block group btrfs: zoned: activate metadata block group on flush_space btrfs: zoned: disable metadata overcommit for zoned btrfs: zoned: introduce space_info->active_total_bytes btrfs: zoned: finish least available block group on data bg allocation btrfs: let can_allocate_chunk return error ...

The AVR32 architecture has been removed from the kernel in commit 26202873, hence clean out the atmel,at32ap-lcdc parts in the atmel_lcdfb.c video driver. AVR32 architecture never supported device tree, hence this code was not used by anybody. Signed-off-by: Hans-Christian Noren Egtvedt <egtvedt@samfundet.no>

The AVR32 architecture has been removed from the kernel in commit 26202873, hence clean out the cdns,at32ap7000-macb compatible entry in Cadence macb Ethernet driver. AVR32 architecture never supported device tree, hence this code was not used by anybody. Updated documentation to match the default entry, no users of cdns,at32ap7000-macb in the kernel tree.

I have changed my overall maintainer email address to the samfundet.no domain, hence update the atmel-ssc module to reflect that. Also remove the AVR32 reference, since the AVR32 architecture no longer exist in the Linux kernel. Signed-off-by: Hans-Christian Noren Egtvedt <egtvedt@samfundet.no>
