Merge tag 'char-misc-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc and other driver updates from Greg KH:
 "Here is the large set of char, misc, and other "small" driver
  subsystem changes for 5.17-rc1.

  Lots of different things are in here for char/misc drivers such as:

   - habanalabs driver updates

   - mei driver updates

   - lkdtm driver updates

   - vmw_vmci driver updates

   - android binder driver updates

   - other small char/misc driver updates

  Also smaller driver subsystems have also been updated, including:

   - fpga subsystem updates

   - iio subsystem updates

   - soundwire subsystem updates

   - extcon subsystem updates

   - gnss subsystem updates

   - phy subsystem updates

   - coresight subsystem updates

   - firmware subsystem updates

   - comedi subsystem updates

   - mhi subsystem updates

   - speakup subsystem updates

   - rapidio subsystem updates

   - spmi subsystem updates

   - virtual driver updates

   - counter subsystem updates

  Too many individual changes to summarize, the shortlog contains the
  full details.

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