Some update suggestions were taken into account
from static source code analysis.
Markus Elfring (5):
Delete an error message for a failed memory allocation in three functions
Adjust 44 checks for null pointers
Delete an unnecessary return statement in skd_pci_remove()
Fix a typo in a comment line in skd_do_inq_page_da()
Use ARRAY_SIZE() in skd_check_status()

Omit an extra message for a memory allocation failure in these functions.
This issue was detected by using the Coccinelle software.

The script “checkpatch.pl” pointed information out like the following.
Comparison to NULL could be written …
Thus fix affected source code places.

The script "checkpatch.pl" pointed information out like the following.
WARNING: void function return statements are not generally useful
Thus remove such a statement in the affected function.
