Hi Tomi,

Thanks for a great cleanup series!

I have tested this in Gen2, Gen3 and Gen4 without noticing any 
regressions. The log is now spammed with the helpful suggestion that the 
CSI-2 TX subdevices shall implement V4L2_CID_LINK_FREQ control. This is 
annoying but out of scope for this series, but would be nice at some 
point.

  [   37.421531] v4l2_get_link_freq: Link frequency estimated using pixel rate: result might be inaccurate
  [   37.430991] v4l2_get_link_freq: Consider implementing support for V4L2_CID_LINK_FREQ in the transmitter driver

For the whole series,
