Fixed:
ERROR: do not use assignment in if condition
ERROR: switch and case should be at the same indent
ERROR: trailing statements should be on next line
WARNING: braces {} are not necessary for single statement blocks
WARNING: simple_strtol is obsolete, use kstrtol instead
Not fixed (false positive):
ERROR: Macros with complex values should be enclosed in parenthesis
Not all fixed (code complexity):
ERROR: do not use assignment in if condition
