+# check for pointless casting of kmalloc return
+ if ($rawline =~ /\*\)[ ]k[czm]alloc/) {
It looks to me like this will catch
foo = (char *) kmalloc(512);
but not
for = (char* )kmalloc(512);
I haven't tried it but how about something like:
if($rawline =~/\(.*\)\s*k[czm]alloc/){
which if I got it right should match the typecast with any combination of
spacing.
+ WARN("No need to cast return value.\n");
Could the warning be more descriptive? This describes what, but it should also describe
why; after all if somebody made this error they may not know they why.
