Subject: [PATCH][next] media: rcar_jpu: remove redundant case statement when c is zero

The case statement where c is zero is redundant because the previous
while loop will only exit if c is non-zero or non-0xff, so c can
never be zero by the time the switch statement is reaced. Clean up
the code by removing it.
