This was missed for the pwm/for-6.8-rc1 PR. I added it to my for-next branch at https://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux.git pwm/for-next now with the intention to send it for inclusion in 6.8-rc after being in next for a few days. > Also "pwm: linux/pwm.h: fix Excess kernel-doc description warning" > (Message-Id: 20231223050621.13994-1-rdunlap@infradead.org) should be > added IMHO. This one was already cared for. Best regards Uwe

devm_add_action_or_reset() already calls the action in the error case.
