In addition set_fmt should first invoked try_fmt to validate the given format before applying it to the hardware. To fix all of these the whole get/try/set ioctl functions had to be reworked. When calculating the bytesperline/stride and sizeimage format member we don't need to locally store the current value of bytesperpixel as it can easily get derived dynamically.
