Fixed:
ERROR: code indent should use tabs where possible
ERROR: do not use assignment in if condition
ERROR: space prohibited after that open parenthesis '('
ERROR: spaces required around that '<' (ctx:VxV)
ERROR: spaces required around that '==' (ctx:VxV)
WARNING: please, no spaces at the start of a line
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead
Not fixed (false positive):
ERROR: Macros with multiple statements should be enclosed in a do - while loop
