[libcamera-devel] [PATCH v5 29/33] ipa: rkisp1: awb: Log means, gains and temperature in debug message

[Laurent Pinchart]

Extend the debug message in Awb::process() to log the means and color
temperature in addition to the gains. This is useful for debugging the
algorithm behaviour. While at it, set the showpoint flag to print a
fixed number of digits after the decimal point, making logs more
readable.
