Fixed:
ERROR: code indent should use tabs where possible
ERROR: do not use assignment in if condition
ERROR: "foo * bar" should be "foo *bar"
ERROR: space required after that ',' (ctx:VxV)
ERROR: spaces required around that ':' (ctx:VxE)
ERROR: spaces required around that '==' (ctx:VxV)
WARNING: braces {} are not necessary for single statement blocks
WARNING: line over 80 characters
WARNING: please, no space before tabs
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WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead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 or not all fixed (code complexity):
ERROR: Macros with complex values should be enclosed in parenthesis
ERROR: do not use assignment in if condition
