Not so nice that you have to make up an error code here. But that's not
your fault but devm_auxiliary_device_create()'s which returns NULL on
error instead of an error pointer.

return 0;

I applied the patch for the upcoming merge window to

https://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux.git pwm/for-next

. Expecting the merge window to open on Sunday that's a bit tight
because I like drivers to be in next for a bit before they enter the
mainline. The major code change is in drivers/hwmon and I assume Guenter
is ok with me taking it for 6.17-rc1. If not, please object, then I'll
not send it to Linus and wait for the 6.18-rc1 PR.


Please go ahead and apply both patches.

Thanks,
Guenter
