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

[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 v8:
- media: uvcvideo: Implement mask for V4L2_CTRL_TYPE_MENU
  New patch
- media: uvcvideo: Use standard names for menus
  New patch

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
