Subject: media: uvcvideo: Fix power line control for SunplusIT camera
Author: Ricardo Ribalda <riba...@chromium.org>
Date: Sat Oct 28 09:55:04 2023 +0200
The device does not implement the power line frequency control
correctly. It is a UVC 1.5 device, but implements the control as a UVC
1.1 device.
Add the corresponding control mapping override.
