py: MappedFrameBuffer: Support non-contextmanager use
Implement non-contextmanager use to MappedFrameBuffer so that we can either: with MappedFrameBuffer(fb) as mfb: ... or mfb = MappedFrameBuffer(fb) mfb.mmap() ... mfb.munmap() While at it, improve the error handling a bit. Note that the mmap() returns self. In other words, one can do this: mfb = MappedFrameBuffer(fb).mmap() ... mfb.munmap() Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
