  This patch serie changes the decoding mode from "exit on error"
to "keep decoding". Using this mode and re-enabling error detection
allow getting error resilience without loosing the ability to report
errors to userland. This have showed great results, but might be a
little more risky since this is not the mode that the reference code
uses and the documentation is very brief. With this in place,
userspace can chose to skip or display corrupted frames depending
on its application requirement. Previsouly, applicaiton would have
had no choice but to present the corrupted frames.

Changes since V1:
	- Removed merged patch
	- Changed usage of pr_debug into v4l2_dbg
	- Fix typos in commit messages and comments
