Currently, there is an out-of-bounds read on array hpetp->hp_dev
in the following for loop:

870         for (i = 0; i < hdp->hd_nirqs; i++)
871                 hpetp->hp_dev[i].hd_hdwirq = hdp->hd_irq[i];

This is due to the recent change from one-element array to
flexible-array member in struct hpets:

104 struct hpets {
	...
113         struct hpet_dev hp_dev[];
114 };

This change affected the total size of the dynamic memory
allocation, decreasing it by one time the size of struct hpet_dev.

Fix this by adjusting the allocation size when calling
struct_size().

 "This is the bulk of GPIO changes for the v5.6 kernel cycle.

  This is a pretty calm cycle so far, nothing special going on really.
  Some more changes will come in from the irqchip and pin control trees.

  I also deleted an orphan include file for FMC that was dangling since
  subsystem was removed.

  Core changes:

   - Document the usecases for the kernelspace vs userspace handling of
     GPIOs.

   - Handle MSI (message signalled interrupts) properly in the core
     hierarchical irqdomain code.

   - Fix a rare race condition while initializing the descriptor array.

  New drivers:

   - Xylon LogiCVC GPIO driver.

   - WDC934x GPIO controller driver.

  Driver improvements:

   - Implemented suspend/resume in the Tegra driver.

   - MPC8xx edge detection fixup.

   - Properly convert ThunderX to use hierarchical irqdomain with
     GPIOLIB_IRQCHIP on top of the revert of the previous buggy
     switchover. This time it works (hopefully).

Pull IMA updates from Mimi Zohar:
 "Two new features - measuring certificates and querying IMA for a file
  hash - and three bug fixes:

   - Measuring certificates is like the rest of IMA, based on policy,
     but requires loading a custom policy. Certificates loaded onto a
     keyring, for example during early boot, before a custom policy has
     been loaded, are queued and only processed after loading the custom
     policy.

   - IMA calculates and caches files hashes. Other kernel subsystems,
     and possibly kernel modules, are interested in accessing these
     cached file hashes.

  The bug fixes prevent classifying a file short read (e.g. shutdown) as
  an invalid file signature, add a missing blank when displaying the
  securityfs policy rules containing LSM labels, and, lastly, fix the
  handling of the IMA policy information for unknown LSM labels"

Pull sound updates from Takashi Iwai:
 "As the diffstat shows we've had again a lot of works done for this
  cycle: the majority of changes are the continued componentization and
  code refactoring in ASoC, the tree-wide PCM API updates and cleanups
  and SOF updates while a few ASoC driver updates are seen, too.

  Here we go, some highlights:

  Core:
   - Finally y2038 support landed to ALSA ABI; some ioctls have been
     extended and lots of tricks were applied
   - Applying the new managed PCM buffer API to all drivers; the API
     itself was already merged in 5.5
   - The already deprecated dimension support in ALSA control API is
     dropped completely now
   - Verification of ALSA control elements to catch API misuses

  ASoC:
   - Further code refactorings and moving things to the component level
   - Lots of updates and improvements on SOF / Intel drivers; now
     including common HDMI driver and SoundWire support
   - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm

  Btrfs: make deduplication with range including the last block work

Pull btrfs updates from David Sterba:
 "Features, highlights:

   - async discard
       - "mount -o discard=async" to enable it
       - freed extents are not discarded immediatelly, but grouped
         together and trimmed later, with IO rate limiting
       - the "sync" mode submits short extents that could have been
         ignored completely by the device, for SATA prior to 3.1 the
         requests are unqueued and have a big impact on performance
       - the actual discard IO requests have been moved out of
         transaction commit to a worker thread, improving commit latency
       - IO rate and request size can be tuned by sysfs files, for now
         enabled only with CONFIG_BTRFS_DEBUG as we might need to
         add/delete the files and don't have a stable-ish ABI for
         general use, defaults are conservative

   - export device state info in sysfs, eg. missing, writeable

   - no discard of extents known to be untouched on disk (eg. after
     reservation)

   - device stats reset is logged with process name and PID that called
     the ioctl

  Fixes:

   - fix missing hole after hole punching and fsync when using NO_HOLES

   - writeback: range cyclic mode could miss some dirty pages and lead
     to OOM

   - two more corner cases for metadata_uuid change after power loss
     during the change

   - fix infinite loop during fsync after mix of rename operations

  Core changes:

   - qgroup assign returns ENOTCONN when quotas not enabled, used to
     return EINVAL that was confusing

   - device closing does not need to allocate memory anymore

   - snapshot aware code got removed, disabled for years due to
     performance problems, reimplmentation will allow to select wheter
     defrag breaks or does not break COW on shared extents

   - tree-checker:
       - check leaf chunk item size, cross check against number of
         stripes
       - verify location keys for DIR_ITEM, DIR_INDEX and XATTR items

   - new self test for physical -> logical mapping code, used for super
     block range exclusion

   - assertion helpers/macros updated to avoid objtool "unreachable
     code" reports on older compilers or config option combinations"
