Subject: media: em28xx: annotate unchecked call to media_device_register() Author: Nikita Zhandarovich <n.zhandarov...@fintech.ru> Date: Fri Jan 12 05:42:26 2024 -0800 Static analyzers generate alerts for an unchecked call to `media_device_register()`. However, in this case, the device will work reliably without the media controller API. Add a comment above the call to prevent future unnecessary changes.
