Merge tag 'driver-core-5.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core and debugfs fixes from Greg KH: "Here are four small driver core / debugfs patches for 5.6-rc3: - debugfs api cleanup now that all debugfs_create_regset32() callers have been fixed up. This was waiting until after the -rc1 merge as these fixes came in through different trees - driver core sync state fixes based on reports of minor issues found in the feature All of these have been in linux-next with no reported issues" * tag 'driver-core-5.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: driver core: Skip unnecessary work when device doesn't have sync_state() driver core: Add dev_has_sync_state() driver core: Call sync_state() even if supplier has no consumers debugfs: remove return value of debugfs_create_regset32()
