Linus Torvalds 5c93506983 pwm changes for 6.8, take 2
The first commit fixes a duplicate cleanup in an error path introduced
 in pwm/for-6.8-rc1~13.
 
 The second cares for an out-of-bounds access. In practise it doesn't
 happen---otherwise someone would have noticed since v5.17-rc1 I
 guess---because the device tree binding for the two drivers using
 of_pwm_single_xlate() only have args->args_count == 1. A device-tree
 that doesn't conform to the respective bindings could trigger that
 easily however.
 
 The third and last one corrects the request callback of the jz4740 pwm
 driver which used dev_err_probe() long after .probe() completed. This is
 conceptually wrong because dev_err_probe() might call
 device_set_deferred_probe_reason() which is nonsensical after the driver
 is bound.

Merge tag 'pwm/for-6.8-2' of gitolite.kernel.org:pub/scm/linux/kernel/git/ukleinek/linux

Pull pwm fixes from Uwe Kleine-König:

 - fix a duplicate cleanup in an error path introduced in
   this merge window

 - fix an out-of-bounds access

   In practise it doesn't happen - otherwise someone would have noticed
   since v5.17-rc1 I guess - because the device tree binding for the two
   drivers using of_pwm_single_xlate() only have args->args_count == 1.

   A device-tree that doesn't conform to the respective bindings could
   trigger that easily however.

 - correct the request callback of the jz4740 pwm driver which used
   dev_err_probe() long after .probe() completed.

   This is conceptually wrong because dev_err_probe() might call
   device_set_deferred_probe_reason() which is nonsensical after the
   driver is bound.

* tag 'pwm/for-6.8-2' of gitolite.kernel.org:pub/scm/linux/kernel/git/ukleinek/linux:
  pwm: jz4740: Don't use dev_err_probe() in .request()
  pwm: Fix out-of-bounds access in of_pwm_single_xlate()

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
