[libcamera-devel] [PATCH 1/2] libcamera: ipu3: Make it easier to read when a request may be completed

It's confusing to read the code and understand that a request is only
completed before being processed by the ImgU if it only contains a
single RAW buffer. Add a boolean variable with a explanatory name to
make this clearer, no functional change.
