      Bluetooth: hci_sync: Fix suspending with wrong filter policy · 96b82af3
      Luiz Augusto von Dentz authored 
      When suspending the scan filter policy cannot be 0x00 (no acceptlist)
since that means the host has to process every advertisement report
waking up the system, so this attempts to check if hdev is marked as
suspended and if the resulting filter policy would be 0x00 (no
acceptlist) then skip passive scanning if thre no devices in the
acceptlist otherwise reset the filter policy to 0x01 so the acceptlist
is used since the devices programmed there can still wakeup be system.

      Bluetooth: btmtk: Fix kernel crash when entering btmtk_usb_suspend · d09009bc
      Chris Lu authored 
      If MediaTek's Bluetooth setup is unsuccessful, a NULL pointer issue
occur when the system is suspended and the anchored kill function
is called. To avoid this, add protection to prevent executing the
anchored kill function if the setup is unsuccessful.

      net: phy: realtek: add support for RTL8366S Gigabit PHY · 225990c4
      Mark Mentovai authored 
      The PHY built in to the Realtek RTL8366S switch controller was
previously supported by genphy_driver. This PHY does not implement MMD
operations. Since commit 9b01c885 ("net: phy: c22: migrate to
genphy_c45_write_eee_adv()"), MMD register reads have been made during
phy_probe to determine EEE support. For genphy_driver, these reads are
transformed into 802.3 annex 22D clause 45-over-clause 22
mmd_phy_indirect operations that perform MII register writes to
MII_MMD_CTRL and MII_MMD_DATA. This overwrites those two MII registers,
which on this PHY are reserved and have another function, rendering the
PHY unusable while so configured.

Proper support for this PHY is restored by providing a phy_driver that
declares MMD operations as unsupported by using the helper functions
provided for that purpose, while remaining otherwise identical to
genphy_driver.

      net: usb: sr9700: fix uninitialized variable use in sr_mdio_read · 08f3a5c3
      Ma Ke authored 
      It could lead to error happen because the variable res is not updated if
the call to sr_share_read_word returns an error. In this particular case
error code was returned and res stayed uninitialized. Same issue also
applies to sr_read_reg.

This can be avoided by checking the return value of sr_share_read_word
and sr_read_reg, and propagating the error if the read operation failed.

Found by code review.

      sysctl: treewide: constify the ctl_table argument of proc_handlers · 78eb4ea2
      Joel Granados authored 
      const qualify the struct ctl_table argument in the proc_handler function
signatures. This is a prerequisite to moving the static ctl_table
structs into .rodata data which will ensure that proc_handler function
pointers cannot be modified.

```

* Code formatting was adjusted in xfs_sysctl.c to comply with code
  conventions. The xfs_stats_clear_proc_handler,
  xfs_panic_mask_proc_handler and xfs_deprecated_dointvec_minmax where
  adjusted.

* The ctl_table argument in proc_watchdog_common was const qualified.
  This is called from a proc_handler itself and is calling back into
  another proc_handler, making it necessary to change it as part of the
  proc_handler migration.

      Pull random number generator updates from Jason Donenfeld:
 "This adds getrandom() support to the vDSO.

  First, it adds a new kind of mapping to mmap(2), MAP_DROPPABLE, which
  lets the kernel zero out pages anytime under memory pressure, which
  enables allocating memory that never gets swapped to disk but also
  doesn't count as being mlocked.

  Then, the vDSO implementation of getrandom() is introduced in a
  generic manner and hooked into random.c.

  Next, this is implemented on x86. (Also, though it's not ready for
  this pull, somebody has begun an arm64 implementation already)

  Finally, two vDSO selftests are added.

  There are also two housekeeping cleanup commits"
