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 Ricardo Ribalda (8): media: uvcvideo: Add missing value for power_line_frequency media: uvcvideo: Add support for per-device control mapping overrides media: uvcvideo: Support minimum for V4L2_CTRL_TYPE_MENU media: uvcvideo: Limit power line control for Quanta UVC Webcam media: uvcvideo: Limit power line control for Chicony Easycamera media: uvcvideo: Limit power line control for Chicony Easycamera media: uvcvideo: Limit power line control for Quanta cameras media: uvcvideo: Limit power line control for Acer EasyCamera drivers/media/usb/uvc/uvc_ctrl.c | 90 ++++++++++++++++++++++++------ drivers/media/usb/uvc/uvc_driver.c | 89 +++++++++++++++++++++++++++++ drivers/media/usb/uvc/uvcvideo.h | 2 + 3 files changed, 165 insertions(+), 16 deletions(-) -- 2.36.1.476.g0c4daa206d-goog
