Subject: media: uvcvideo: Refactor Power Line Frequency limit selection
Author: Ricardo Ribalda <riba...@chromium.org>
Date: Mon Jun 10 23:09:53 2024 +0000
Move the PLF mapping logic to its own mapping filter function. This
commit does not introduce any new functionality to the logic, it is just
a preparation patch.
