[PATCH v7 0/8] uvcvideo: Fix handling of power_line_frequency

From: Ricardo Ribalda

Hello,

This series is a new version of "[PATCH v3 0/7] uvcvideo: Fix handling
of power_line_frequency", with an attempt to generalize the
UVC_QUIRK_LIMITED_POWERLINE quirk that it introduced and turn it into a
control mappings override mechanism.

The goal is still to support the UVC 1.5 power line frequency control
extra option (patch 1/7), and work around an issue with devices that do
not implement support for disabling the power line frequency (patches
2/7 to 7/7).


Changelog v7:
- Support minimum for V4L2_CTRL_TYPE_MENU
Fix uvc_query_v4l2_menu

Changelog v6:
- Add support for per-device control mapping overrides
Fix invalid memory access
- Support minimum for V4L2_CTRL_TYPE_MENU
New patch
- Limit power line control for Quanta UVC Webcam
Fix id
