Merge tag 'char-misc-6.11-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 "big" set of char/misc and other driver subsystem changes
  for 6.11-rc1. Nothing major in here, just loads of new drivers and
  updates. Included in here are:

   - IIO api updates and new drivers added

   - wait_interruptable_timeout() api cleanups for some drivers

   - MODULE_DESCRIPTION() additions for loads of drivers

   - parport out-of-bounds fix

   - interconnect driver updates and additions

   - mhi driver updates and additions

   - w1 driver fixes

   - binder speedups and fixes

   - eeprom driver updates

   - coresight driver updates

   - counter driver update

   - new misc driver additions

   - other minor api updates

  All of these, EXCEPT for the final Kconfig build fix for 32bit
  systems, have been in linux-next for a while with no reported issues.
  The Kconfig fixup went in 29 hours ago, so might have missed the
  latest linux-next, but was acked by everyone involved"
