ERROR: space required after that ',' (ctx:VxV)
ERROR: spaces required around that '?' (ctx:VxE)
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: trailing statements should be on next line
WARNING: line over 80 characters
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead
