Subject[PATCH 04/16] media: vimc: cap: Change vimc_cap_device.format type
Date
vimc_cap_device.format field was defined as v4l2_pix_format,
a struct to handle single planar pixel formats. It turns out that
if v4l2_format is used, we can reuse functions for both
v4l2_pix_format and v4l2_pix_format_mplane. This change will
help at future commits implementing multiplanar pixel
format support.
