commit 147359e23e5c9652ff8c5a98a51a7323bd51c94a upstream.

Device nodes accessed via of_get_compatible_child() require
of_node_put() to be called when the node is no longer required to avoid
leaving a reference to the node behind, leaking the resource.

In this case, the usage of 'tnode' is straightforward and there are no
error paths, allowing for a single of_node_put() when 'tnode' is no
longer required.

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"

Pull pwm updates from Uwe Kleine-König:
 "This contains the usual mix of fixes, cleanups, two new drivers and
  several dt binding updates. The fixes are for minor issues that are
  already old (4.11-rc1 and 3.9-rc1) and were found by code review and
  not during usage, so I didn't sent them for earlier inclusion.

  The changes to include/linux/mfd/stm32-timers.h and
  drivers/counter/stm32-timer-cnt.c are part of an immutable branch that
  will also be included in the mfd and counter pulls. It changes some
  register definitions and affects the pwm-stm32 driver.

The ti_eqep_count_from_counter() function is just a wrapper around
counter_priv(). counter_priv() can be used directly, so we don't need
the wrapper function. Remove it.
