2022-01-22:

• reworked multi-camera support for Pinephone on top of upstream changes
  (media device graph changed quite a bit upstream, you may need to update the
  userspace camera apps for them to continue working)

Seems the original Pinephone is affected by this. Pinephone Pro is still fine with 6.2 kernel series.
