Fixed:
ERROR: code indent should use tabs where possible
ERROR: do not use assignment in if condition
ERROR: else should follow close brace '}'
ERROR: space prohibited after that open parenthesis '('
ERROR: space required after that ',' (ctx:VxV)
ERROR: spaces required around that '<=' (ctx:VxV)
ERROR: spaces required around that '<' (ctx:VxV)
ERROR: spaces required around that '==' (ctx:VxV)
ERROR: spaces required around that '=' (ctx:VxV)
ERROR: spaces required around that ':' (ctx:VxW)
ERROR: trailing statements should be on next line
WARNING: braces {} are not necessary for any arm of this statement
WARNING: do not add new typedefs
WARNING: please, no space before tabs
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead
Modify multi-line comments to follow Documentation/CodingStyle.
Not fixed (unknown impact):
WARNING: msleep < 20ms can sleep for up to 20ms
