Merge tag 'char-misc-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc 

Pull Char/Misc/IIO driver updates from Greg KH:
 "Here is the "big" set of char/misc/iio and other smaller driver
  subsystem updates for 6.14-rc1. Loads of different things in here this
  development cycle, highlights are:

   - ntsync "driver" to handle Windows locking types enabling Wine to
     work much better on many workloads (i.e. games). The driver
     framework was in 6.13, but now it's enabled and fully working
     properly. Should make many SteamOS users happy. Even comes with
     tests!

   - Large IIO driver updates and bugfixes

   - FPGA driver updates

   - Coresight driver updates

   - MHI driver updates

   - PPS driver updatesa

   - const bin_attribute reworking for many drivers

   - binder driver updates

   - smaller driver updates and fixes

  All of these have been in linux-next for a while with no reported
  issues"
