Hi,

The recently release Linux v5.2 changes the vimc drivers behavior in a
way which breaks libcameras vimc pipeline and some of our tests. This
small series aims to solve this and keep libcamera functioning on both
v5.1 (and earlier) and v5.2.

Patch 1/4 is a small preparation patch. While 2/4 and 3/4 fixes issues
introduced by [1] and finally 4/4 fixes an issue introduced by [2]. The
whole series is tested on v5.1 and v5.2 on top of libcamera master
branch and all tests pass again.

1. 85ab1aa1fac17bcd ("media: vimc: deb: fix default sink bayer format")
2. b6c61a6c37317efd ("media: vimc: propagate pixel format in the stream")

Niklas Söderlund (4):
  libcamera: pipeline: vimc: Initialize device pointers
  libcamera: pipeline: vimc: Set media bus formats for sensor and
    debayer
  tests: v4l2_videodevice: Set media bus and pixel formats for vimc
  tests: camera-sensor: Test using invalid media bus format
