This version is a bit of a whopper. This version brings a few new checks, improvements to a number of checks mostly through modifications to the way types are parsed, several fixes to quote/comment handling, as well as the usual slew of fixes for false positives. Of note: - return is not a function and is now reported, - preprocessor directive detection is loosened to match C99 standard, - we now intuit new type modifiers, and - comment handling is much improved Andy Whitcroft (18): Version: 0.19 fix up a couple of missing newlines in reports colon to parenthesis spacing varies on asm values: #include is a preprocessor statement quotes: fix single character quotes at line end add typedef exception for the non-pointer "function types" kerneldoc parameters must be on one line, relax line length types: word boundary is not always required improved #define bracketing reports uninitialized_var is an annotation not a function name possible types: add possible modifier handling possible types: fastcall is a type modifier types: unsigned is not a modifier on all types static/external initialisation to zero should allow modifiers checkpatch: fix recognition of preprocessor directives -- part 2 comments: fix inter-hunk comment tracking return is not a function do not report include/asm/foo.h use in include/linux/foo.h return is not a function -- tighten test [jengelh@computergmbh.de: fix recognition of preprocessor directives] Signed-off-by:Andy Whitcroft <apw@shadowen.org> Cc: Jan Engelhardt <jengelh@computergmbh.de> Signed-off-by:
