[libcamera-devel] [PATCH v4 5/8] libcamera: v4l2_subdevice: Update crop/compose rectangle

[Jacopo Mondi]

Update the crop/compose rectangle provided to setCrop()/setCompose()
methods with the rectangle sizes set by the device driver after a
S_SELECTION ioctl operation.

While at there, fix the use of 'top' and 'left' field of the selection
rectangle, which where wrongly used.
