[libcamera-devel] [PATCH v2 1/2] libcamera: camera: fix validateColorSpaces to choose the correct "main" colour space

[David Plowman]

The intention is that the "main" colour space is the colour space of
the largest non-raw stream. Unfortunately the use of "config_[i].size"
is clearly incorrect, and has been copied from prior versions of the
code. This small change merely corrects the error.
