Two update suggestions were taken into account
from static source code analysis.
Markus Elfring (2):
Adjust ten function calls together with a variable assignment
Use common error handling code in two functions

The script "checkpatch.pl" pointed information out like the following.
ERROR: do not use assignment in if condition
Thus fix the affected source code places.

Add jump targets so that a bit of exception handling can be better reused
at the end of these functions.
This issue was detected by using the Coccinelle software.
