Three update suggestions were taken into account
from static source code analysis.
Markus Elfring (3):
Delete an error message for a failed memory allocation
Improve a size determination
Adjust two function calls together with a variable assignment

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
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 the affected source code places.
