[PATCH 0/2] media: bcm2835-unicam: Fix compilation errors and warnings

[Laurent Pinchart]

Hello,

This small patch series fixes two compilation issues reported by the
kernel test robot ([1]) in the newly merged Unicam driver. The fixes are
meant for v6.10.

[PATCH 1/2] media: bcm2835-unicam: Drop usage of of_match_ptr()

[Laurent Pinchart]

Using of_match_ptr() to set the .of_match_table field of the device
driver results in the unicam_of_match table being unused on non-OF
platforms, causing a compilation warning. Fix it by dropping usage of
of_match_ptr(), which can be done because the .of_match_table field is
part of the device_driver structure regardless of whether or not
CONFIG_OF is selected.

[PATCH 2/2] media: bcm2835-unicam: Include v4l2-subdev.h

[Laurent Pinchart]

The unicam driver uses the v4l2_subdev structure. Include the
corresponding header instead of relying on indirect includes.

Assuming your v2 will be merged in v6.10.
