[ Upstream commit 4020d1cc ] The Asus USB DAC is a USB type-C audio dongle for connecting to the headset and headphone. The volume minimum value -23040 which is 0xa600 in hexadecimal with the resolution value 1 indicates this should be endianness issue caused by the firmware bug. Add a volume quirk to fix the volume control problem. Also fixes this warning: Warning! Unlikely big volume range (=23040), cval->res is probably wrong. [5] FU [Headset Capture Volume] ch = 1, val = -23040/0/1 Warning! Unlikely big volume range (=23040), cval->res is probably wrong.

[ Upstream commit 665e7c73 ] Avoid LDB and IPU DI clocks both using the same parent. LDB requires pasthrough clock to avoid breaking timing while IPU DI does not. Force IPU DI clocks to use IMX6QDL_CLK_PLL2_PFD0_352M as parent and LDB to use IMX6QDL_CLK_PLL5_VIDEO_DIV. This fixes an issue where attempting atomic modeset while using HDMI and display port at the same time causes LDB clock programming to destroy the programming of HDMI that was done during the same modeset.

[ Upstream commit 1d0c7bb2 ] The IPU that drives HDMI must have its pre_sel set to pll2_pfd_396m to avoid stepping on the LVDS output's toes, as the PLL can't be clocked to the pixel clock and to the LVDS serial clock (3.5*pixel clock) at the same time. As we are using ipu1_di0 and ipu2_di0, ensure both are switched to to pll2_pfd2_396m to avoid issues. The LDB driver will switch the required IPU to ldb_di1 when it uses it to drive LVDS.

[ Upstream commit 2712c91a ] On the Lenovo ThinkPad Twist S230u (3347-4HU) with BIOS version "GDETC1WW (1.81 ) 06/27/2019", the keyboard, Synaptics TouchPad, and TrackPoint either do not function or stop functioning a few minutes after boot. This problem has been noted before, perhaps only occurring with BIOS 1.57 and later.[1][2][3][4][5] Odds of a BIOS fix appear to be low: 1.57 was released over 6 years ago and although the [BIOS changelog] notes "Fixed an issue of UEFI touchpad/trackpoint/keyboard/touchscreen" in 1.58, it appears to be insufficient. Setting i8042.reset=1 or adding 33474HU to the reset list avoids the issue on my system from either warm or cold boot.

[ Upstream commit 7bb0c533 ] There is a potential race in fscache operation enqueuing for reading and copying multiple pages from cachefiles to netfs. The problem can be seen easily on a heavy loaded system (for example many processes reading files continually on an NFS share covered by fscache triggered this problem within a few minutes). The race is due to cachefiles_read_waiter() adding the op to the monitor to_do list and then then drop the object->work_lock spinlock before completing fscache_enqueue_operation(). Once the lock is dropped, cachefiles_read_copier() grabs the op, completes processing it, and makes it through fscache_retrieval_complete() which sets the op->state to the final state of FSCACHE_OP_ST_COMPLETE(4). When cachefiles_read_waiter() finally gets through the remainder of fscache_enqueue_operation() it sees the invalid state, and hits the ASSERTCMP and the following oops is seen: [ 2259.612361] FS-Cache: [ 2259.614785] FS-Cache: Assertion failed [ 2259.618639] FS-Cache: 4 == 5 is false [ 2259.622456] ------------[ cut here ]------------ [ 2259.627190] kernel BUG at fs/fscache/operation.c:70! ...

[ Upstream commit 4ed0c308 ] Before this patch, function gfs2_quota_lock checked if it was called from a privileged user, and if so, it bypassed the quota check: superuser can operate outside the quotas. That's the wrong place for the check because the lock/unlock functions are separate from the lock_check function, and you can do lock and unlock without actually checking the quotas. This patch moves the check to gfs2_quota_lock_check. Signed-off-by:

[ Upstream commit 0cf253ee ] The driver currently leaves GPIO IRQs unmasked even when the GPIO IRQ client has released the GPIO IRQ. This allows the HW to raise IRQs, and SW to process them, after shutdown. Fix this by masking the IRQ when it's shut down. This is usually taken care of by the irqchip core, but since this driver has a custom irq_shutdown implementation, it must do this explicitly itself. Signed-off-by:

[ Upstream commit 17d00e83 ] When FW response to commands is very slow and all command entries in use are waiting for completion we can have a race where commands can get timeout before they get out of the queue and handled. Timeout completion on uninitialized command will cause releasing command's buffers before accessing it for initialization and then we will get NULL pointer exception while trying access it. It may also cause releasing buffers of another command since we may have timeout completion before even allocating entry index for this command. Add entry handling completion to avoid this race.

[ Upstream commit d3e8e4c1 ] Commit bdf6fa52 ("sctp: handle association restarts when the socket is closed.") starts shutdown when an association is restarted, if in SHUTDOWN-PENDING state and the socket is closed. However, the rationale stated in that commit applies also when in SHUTDOWN-SENT state - we don't want to move an association to ESTABLISHED state when the socket has been closed, because that results in an association that is unreachable from user space. The problem scenario: 1. Client crashes and/or restarts. 2. Server (using one-to-one socket) calls close(). SHUTDOWN is lost. 3. Client reconnects using the same addresses and ports. 4. Server's association is restarted. The association and the socket move to ESTABLISHED state, even though the server process has closed its descriptor. Also, after step 4 when the server process exits, some resources are leaked in an attempt to release the underlying inet sock structure in ESTABLISHED state: IPv4: Attempt to release TCP socket in state 1 00000000377288c7 Fix by acting the same way as in SHUTDOWN-PENDING state. That is, if an association is restarted in SHUTDOWN-SENT state and the socket is closed, then start shutdown and don't move the association or the socket to ESTABLISHED state.

[ Upstream commit a6211caa ] Commit adb03115 ("net: get rid of an signed integer overflow in ip_idents_reserve()") used atomic_cmpxchg to replace "atomic_add_return" inside the function "ip_idents_reserve". The reason was to avoid UBSAN warning. However, this change has caused performance degrade and in GCC-8, fno-strict-overflow is now mapped to -fwrapv -fwrapv-pointer and signed integer overflow is now undefined by default at all optimization levels[1]. Moreover, it was a bug in UBSAN vs -fwrapv /-fno-strict-overflow, so Let's revert it safely. [1] https://gcc.gnu.org/gcc-8/changes.htmlSuggested-by:

commit ffca476a upstream. In the case of get_user_pages_fast() returning fewer pages than requested, rio_dma_transfer() does not quite do the right thing. It attempts to release all the pages that were requested, rather than just the pages that were pinned. Fix the error handling so that only the pages that were successfully pinned are released.

commit 34625c19 upstream. In the "gb_tty_set_termios" function the "newline" variable is declared but not initialized. So the "flow_control" member is not initialized and the OR / AND operations with itself results in an undefined value in this member. The purpose of the code is to set the flow control type, so remove the OR / AND self operator and set the value directly.

commit 5e4f99a6 upstream. If the serial interface is used, the 8-bit address should be latched using the rising edge of the WR/FSYNC signal. This basically means that a CS change is required between the first byte sent, and the second one. This change splits the single-transfer transfer of 2 bytes into 2 transfers with a single byte, and CS change in-between. Note fixes tag is not accurate, but reflects a point beyond which there are too many refactors to make backporting straight forward.

[ Upstream commit b14c9490 ] This reverts commit df5db5f9. This patch fixes a regression: patch df5db5f9 allowed function run_queue() to bypass its call to do_xmote() if revokes were queued for the glock. That's wrong because its call to do_xmote() is what is responsible for calling the go_sync() glops functions to sync both the ail list and any revokes queued for it. By bypassing the call, gfs2 could get into a stand-off where the glock could not be demoted until its revokes are written back, but the revokes would not be written back because do_xmote() was never called. It "sort of" works, however, because there are other mechanisms like the log flush daemon (logd) that can sync the ail items and revokes, if it deems it necessary. The problem is: without file system pressure, it might never deem it necessary. Signed-off-by:
