Subject: [PATCH v2] media: uvcvideo: Fix power line control for Shine-Optics Camera
Date: Mon, 08 Jan 2024 14:04:16 +0000 [thread overview]
Message-ID: <20240108-shine-v2-1-ddff959dab89@chromium.org> (raw)
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.
