From: Guenter Roeck <linux@xxxxxxxxxxxx>
Fixed:
WARNING: line over 80 characters
WARNING: simple_strtol is obsolete, use kstrtol instead
Modify multi-line comments to follow Documentation/CodingStyle.
Not fixed (false positive):
ERROR: Macros with multiple statements should be enclosed in a do - while loop
