       "Here is a single SPDX fixup for 5.5-rc1
      
        It resolves an issue where we had missed a few .h files with the

        It's a bit later in the merge window than normal as I wanted to make
        sure some last-minute patches applied to it were all sane. They seem
        to be :)
      
        There's a lot of little stuff in here, for the tty core, and for lots
        of serial drivers:

           implement the Link Training bit (Remi Pommarel)

       "The main changes in the timer code in this cycle were:
      
         - Clockevent updates:
      
            - timer-of framework cleanups. (Geert Uytterhoeven)
      
            - Use timer-of for the renesas-ostm and the device name to prevent
              name collision in case of multiple timers. (Geert Uytterhoeven)
      
            - Check if there is an error after calling of_clk_get in asm9260
              (Chuhong Yuan)
      
         - ABI fix: Zero out high order bits of nanoseconds on compat
           syscalls. This got broken a year ago, with apparently no side
           effects so far.
      
           Since the kernel would use random data otherwise I don't think we'd
           have other options but to fix the bug, even if there was a side
           effect to applications (Dmitry Safonov)
      
         - Optimize ns_to_timespec64() on 32-bit systems: move away from
           div_s64_rem() which can be slow, to div_u64_rem() which is faster
           (Arnd Bergmann)
      
         - Annotate KCSAN-reported false positive data races in
           hrtimer_is_queued() users by moving timer->state handling over to
           the READ_ONCE()/WRITE_ONCE() APIs. This documents these accesses
           (Eric Dumazet)
      
         - Misc cleanups and small fixes"
      
      [ I undid the "ABI fix" and updated the comments instead. The reason
        there were apparently no side effects is that the fix was a no-op.
      
        The updated comment is to say _why_ it was a no-op.    - Linus ]

      Pull XFS updates from Darrick Wong:
       "For this release, we changed quite a few things.
      
        Highlights:
      
         - Fixed some long tail latency problems in the block allocator
      
         - Removed some long deprecated (and for the past several years no-op)
           mount options and ioctls
      
         - Strengthened the extended attribute and directory verifiers
      
         - Audited and fixed all the places where we could return EFSCORRUPTED
           without logging anything
      
         - Refactored the old SGI space allocation ioctls to make the
           equivalent fallocate calls
      
         - Fixed a race between fallocate and directio
      
         - Fixed an integer overflow when files have more than a few
           billion(!) extents
      
         - Fixed a longstanding bug where quota accounting could be incorrect
           when performing unwritten extent conversion on a freshly mounted fs
      
         - Fixed various complaints in scrub about soft lockups and
           unresponsiveness to signals
      
         - De-vtable'd the directory handling code, which should make it
           faster
      
         - Converted to the new mount api, for better or for worse
      
         - Cleaned up some memory leaks
      
        and quite a lot of other smaller fixes and cleanups.
      
        A more detailed summary:
      
         - Fill out the build string
      
         - Prevent inode fork extent count overflows
      
         - Refactor the allocator to reduce long tail latency
      
         - Rework incore log locking a little to reduce spinning
      
         - Break up the xfs_iomap_begin functions into smaller more cohesive
           parts
      
         - Fix allocation alignment being dropped too early when the
           allocation request is for more blocks than an AG is large
      
         - Other small cleanups
      
         - Clean up file buftarg retrieval helpers
      
         - Hoist the resvsp and unresvsp ioctls to the vfs
      
         - Remove the undocumented biosize mount option, since it has never
           been mentioned as existing or supported on linux
      
         - Clean up some of the mount option printing and parsing
      
         - Enhance attr leaf verifier to check block structure
      
         - Check dirent and attr names for invalid characters before passing
           them to the vfs
      
         - Refactor open-coded bmbt walking
      
         - Fix a few places where we return EIO instead of EFSCORRUPTED after
           failing metadata sanity checks
      
         - Fix a synchronization problem between fallocate and aio dio
           corrupting the file length
      
         - Clean up various loose ends in the iomap and bmap code
      
         - Convert to the new mount api
      
         - Make sure we always log something when returning EFSCORRUPTED
      
         - Fix some problems where long running scrub loops could trigger soft
           lockup warnings and/or fail to exit due to fatal signals pending
      
         - Fix various Coverity complaints
      
         - Remove most of the function pointers from the directory code to
           reduce indirection penalties
      
         - Ensure that dquots are attached to the inode when performing
           unwritten extent conversion after io
      
         - Deuglify incore projid and crtime types
      
         - Fix another AGI/AGF locking order deadlock when renaming
      
         - Clean up some quota typedefs
      
         - Remove the FSSETDM ioctls which haven't done anything in 20 years
      
         - Fix some memory leaks when mounting the log fails
      
         - Fix an underflow when updating an xattr leaf freemap
      
         - Remove some trivial wrappers
      
         - Report metadata corruption as an error, not a (potentially) fatal
           assertion

           need to get maintainers to fill in the profiles...
      
         - A reworking of the parallel build setup to work better with a
           variety of systems (and to not take over huge systems entirely in
           particular).
      
         - The MAINTAINERS file is now converted to RST during the build.
           Hopefully nobody ever tries to print this thing, or they will need
           to load a lot of paper.
      
         - A script and documentation making it easy for maintainers to add

      platform/chrome: wilco_ec: fix use after free issue · 856a0a6e
      Wen Yang authored
      This is caused by dereferencing 'dev_data' after put_device() in
      the telem_device_remove() function.
      This patch just moves the put_device() down a bit to avoid this
      issue.
      
      Fixes: 1210d1e6 ("platform/chrome: wilco_ec: Add telemetry char device interface")
