Re: [PATCH] media: v4l2-dev: fix media controller registration error handling

[Shih-Sheng Yang]

Hi Laurent,

Thank you for the review.

I've addressed this in v2 by moving the NULL check into
media_devnode_remove() and by using device_unregister() in
__video_register_device(), as device_register() has already succeeded
there.

I also checked the other media_devnode_remove() callers. I didn't find
another caller with the same failure pattern or an immediate risk that
requires changing the helper API. Since changing media_devnode_remove()
to take a pointer-to-pointer would affect a wider set of callers, I have
left that out of v2. I can add it if you prefer.

Regards,
Shih-Sheng
