From b5f5933a6ab63725aedfb92f015007d4ccd33a55 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 23 Jul 2010 07:09:20 -0300 Subject: [PATCH] V4L/DVB: au0828: move dereference below sanity checks This function has sanity checks to make sure that "dev" is non-null. I moved the dereference down below the checks. In the current code "dev" is never actually null.
