Add a jump target so that a bit of exception handling can be better reused
at the end of this function.
Have you actually tried to see if there's any change in the resulting
object code? I've looked at ARM gcc 4.8.5's output and it didn't really change
-- gcc was able to optimize these repetitive assignments pretty well...
This issue was detected by using the Coccinelle software.

The only good thing is that looking at the assembly, I was able to figure
out that 'ndev' check at 'out_release' is futile... :-)
