* Add a jump target so that a bit of exception handling can be better reused at the end of this function.
This issue was detected by using the Coccinelle software.
* The script "checkpatch.pl" pointed information out like the following.
ERROR: do not use assignment in if condition
Thus fix a few source code places.
