Do you intend to send it to Linus during the current cycle? Best regards Uwe

If you continue to be silent about this (here and at https://lore.kernel.org/linux-pwm/20231121112029.gyv3gqirlycysyr4@pengutronix.de) I intend to send a PR to Linus with this fix on Friday next week.

When 119a508c4dc9 ("pwm: bcm2835: Add support for suspend/resume") was sent out on October 11th,, there was still a call to platform_set_drvdata() which would ensure that the driver private data structure could be used in bcm2835_pwm_{suspend,resume}. A cleanup now merged as commit commit 2ce7b7f6704c ("pwm: bcm2835: Simplify using devm functions") removed that call which would now cause a NPD in bcm2835_pwm_{suspend,resume} as a consequence.
