            Bug ID: 210767
           Summary: uvcvideo: Webcam (1f3a:100e) stopped working after
                    8a652a17e3c005dcdae31b6c8fdf14382a29cbbe
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.10.1-2.g8f3d468
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: USB
          Assignee: drivers_usb@kernel-bugs.kernel.org
          Reporter: doerges@pre-sense.de
                CC: tiwai@suse.de
        Regression: Yes

The device in question is

  Renkforce RF AC4K 300 Action Cam 4K

https://www.conrad.de/de/p/action-cam-renkforce-rf-ac-4k-webcam-4k-wlan-wasserfest-staubgeschuetzt-1577043.html


When connected via USB to a PC, it offers two modes:
 - mass storage
 - camera


When set to webcam mode it identifies as:
  [34367.545510] uvcvideo: Found UVC 1.00 device Android (1f3a:100e)


I tested against 5.10.1-2.g8f3d468.


With 8a652a17e3c005dcdae31b6c8fdf14382a29cbbe
(https://raw.githubusercontent.com/SUSE/kernel-source/openSUSE-15.2/patches.suse/media-uvcvideo-Ensure-all-probed-info-is-returned-to.patch)
the device stopped working in camera mode, i.e. no more video capture.


When reversing the above patch, the device is working as expected.
