checkpatch: improve get_quoted_string for TRACE_EVENT macros The get_quoted_string function does not expect invalid arguments. The $stat test can return non-statements for complicated macros like TRACE_EVENT. Allow the $stat block and test for vsprintf misuses to exceed the actual block length and possibly test invalid lines by validating the arguments of get_quoted_string. Return "" if either get_quoted_string argument is undefined. Miscellanea: o Properly align the comment for the vsprintf extension test Link: http://lkml.kernel.org/r/9e9725342ca3dfc0f5e3e0b8ca3c482b0e5712cc.1520356392.git.joe@perches.com Signed-off-by: Joe Perches <joe@perches.com> Reported-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
