[libcamera-devel] [PATCH v2 1/8] libcamera: Use PixelFormat instead of unsigned int where appropriate
Niklas Söderlund

Tue Mar 17 04:52:32 CET 2020
Use the PixelFormat instead of unsigned int where a pixel format is to
be used. PixelFormat is defined as an unsigned int but is about to be
turned into a class to add functionality.
There is no functional change in this patch.
