Looks great... however I notice a few obvious false positives in the
example log:

 > Don't init statics to 0/NULL:
 > 94312:+static const struct in6_addr in6addr_v4mapped = { { { [10] = 0xff, [11] = 0xff } } };

ummm?

 > 137054:+static uint32_t drvr_ver  = 0x02200207;

that ain't zero...

 > 230079:+                path->static_rate = 0;

and that ain't a static variable.

I guess trying to parse C in a regexp is a little tricky.

Also, it would be nice to be able to do something like

    git diff v2.6.20..|perl ~/checkpatch.pl -

rather than having to create a temp file -- as it stands that command
produces

    unknown option: -
    usage: findbugs.pl [-options] file(s)
      -allsource : check entire source file, not just '+' patch lines
      -pedantic : TBD
      -style : TBD
      -v, --verbose : verbose
      -h, --help : this help text
    Version: 002

And even worse

    git diff v2.6.20..|perl ~/checkpatch.pl

just silently does nothing (maybe a "no input files" warning would be
a good clue for people).
