Hello Linus,

the following changes since commit 7afc0e7f681e6efd6b826f003fc14c17b5093643:

  pwm: jz4740: Don't use dev_err_probe() in .request() (2024-01-12 18:25:05 +0100)

The commits are in next since next-20240117 only, but they are small
and obvious enough to qualify for inclusion IMHO.

Please pull this for v6.8-rc1.

Thanks to Sean for his contribution to this PR.

Best regards
Uwe

----------------------------------------------------------------
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.
