From 3328d9752f3796a5f5f8695d27a175c34407a5ed Mon Sep 17 00:00:00 2001 From: Adrian Bunk Date: Thu, 18 Oct 2007 12:53:07 +0200 Subject: [PATCH] USB rio500.c: fix check-after-use The Coverity checker spotted that we have already oops'ed if "dev" was NULL in these places. Since "dev" being NULL isn't possible at these places this patch removes the NULL checks. Additionally, I've fixed the formatting of the if's.
