Subject: [PATCH] compiler warnings in framebuffer drivers
Date: Wed, 14 Nov 2001 23:26:13 +0100	[thread overview]
Message-ID: <20011114232613.625ed599.l.s.r@web.de> (raw)

Hi,

this patch removes all those compiler warnings that were introduced with
the anti-strtok patch some time ago. It's against kernel 2.4.15-pre4. I
sent you similar ones but it seems they got lost. Which makes me
suspicious: is there something wrong with this patch that prevents it
from being applied?

OK, additionally to adding some parentheses this patch corrects a minor
issue by inserting code like this at appropriate places:

+		if (!*this_opt)
+			continue;

This lets the parameter parsing code skip over empty tokens, just like
strtok did implicitely. It's purely cosmetic - I'd send you a patch
without this 'feature', if you like.

Patch is untested, but at least it compiles. Please, apply.

René
