[PATCH v3 00/13] IPU6 driver cleanups and fixes

[Sakari Ailus <sakari.ailus@linux.intel.com>]

Hello all,

This small set contains cleanups and fixes for the IPU6 driver. I'm
preparing a larger set of improvements in the IPU6 driver on top of the
metadata series (I'll post an update soonish) so consider this to be
preparation for that.

since v2:

- Factor in Mehdi's comments:

  - Rework commit message of "media: ipu6: Remove redundant streaming
    start via buffer queueing" patch a little.

  - Also remove IPU6_ISYS_BUFFER_LIST_FL_SET_STATE flag (patch "media:
    ipu6: Drop error argument from ipu6_isys_stream_start()").

since v1:

- Fix some intra-set compilation breakage and remove a now-redundant
  variable.

- Fix missing assignment of ret in ipu6_isys_link_fmt_validate() (includes
  a cleanup, too).

Sakari Ailus (13):

    list
