Just thought I'd point out that as this includes the linux-iio
list sashiko took a look at it. Quite a few things and at least
the first one I looked at was valid (a dereference before a validity
check)

https://sashiko.dev/#/patchset/20260420-rk3576-pwm-v5-0-ae7cfbbe5427%40collabora.com

Whilst this tool does generate some false positives, it also finds
quite a few things it seems us humans fail to spot.
