[libcamera-devel] [PATCH] qcam: viewfinder: Print message to report format converter usage

[Laurent Pinchart]

Print an info message when initializing the viewfinder to report if the
format converter is used or if zero-copy is enabled. This is useful to
notify of a possible impact on performances.
