Isn't it enough to just match $stat and do fix for line (that in
some cases will just not match)?


One more thing
I noticed funny behavior about $stat matches -
it reports the same error several times (including as "scope" whole file)
Is it feature or "feature" or I missed something?

Ex. file:
-------------- cut
int foo(void)
{
baz();
memset(a, b, 0);
bar();
}
-------------- cut

Output of (@master)

-------------- cut
$ scripts/checkpatch.pl -f test42.c --types MEMSET
ERROR: memset to 0's uses 0 as the 2nd argument, not the 3rd
#1: FILE: test42.c:1:
+int foo(void)
{
baz();
memset(a, b, 0);
bar();
}

ERROR: memset to 0's uses 0 as the 2nd argument, not the 3rd
#2: FILE: test42.c:2:
+{
baz();
memset(a, b, 0);
bar();
}

ERROR: memset to 0's uses 0 as the 2nd argument, not the 3rd
#4: FILE: test42.c:4:
+memset(a, b, 0);

total: 3 errors, 0 warnings, 6 lines checked

NOTE: Used message types: MEMSET

test42.c has style problems, please review.

If any of these errors are false positives, please report
them to the maintainer, see CHECKPATCH in MAINTAINERS.
