update checkpatch.pl to version 0.13
This version brings a large number of fixes which have built up over
the Christmas period. Mostly these are fixes for false positives, both
through improvments to unary checks and possible type detection. It
also brings new checks for while location and CVS keywords. Of note:
- a number of fixes to unary detection
- detection of a number of new forms of types to improve type matching
- better inline handling
- recognision of '%' as an operator
Andy Whitcroft (28):
Version: 0.13
unary detection: maintain bracket state across lines
move to pre-sanitising the entire file
the text of a #error statement should be treated like it is in quotes
line sanitisation needs to target double backslash correctly
tighten comment guestimation for lines starting ' * '
debug: add a debug framework
prevent unclosed single quotes from spreading
add % as an operator
the text of a #warning statement should be treated like it is in
quotes
possible matching applies in typedefs
single statement block checks must not trigger when two or more
statements
possible types: local variables may also be const
treat inline as a type attribute to even when out of place
possible types: sparse annotations are valid indicators
possible types: beef up the possible type testing
check for hanging while statements on the wrong line
utf8 checks need to occur against the raw lines
function brace checks should use any whitespece matches
comments should take up space in the line when sanitised
remove debugging from if assignment checks
possible types -- ensure we detect all pointer casts
fix tests for function spacing in the presence of #define
clean up the UTF-8 error message to be clearer
test-lib: invert the status report, output success counts
detect and report CVS keywords
tests: break out tests
Add $Id$ to the CVS keyword checks
Benny Halevy (1):
checkpatch.pl: recognize the #elif preprocessor directive
Geert Uytterhoeven (1):
print the filenames of patches where available
Mauro Carvalho Chehab (1):
Fix missing \n in checkpatch.pl
