From e94fa28f137813c2f6e05470b41bd8f3c5422a04 Mon Sep 17 00:00:00 2001 From: Florin Malita Date: Mon, 16 Jul 2007 11:50:53 -0400 Subject: [PATCH] USB: mos7720, mos7840: remove redundant urb check Coverity (1709, 1710, 1711, 1712, 1713) actually flagged these as REVERSE_INULLs (NULL check performed after dereference). But looking at the other drivers I can't see any similar tests and the USB core already makes sure urb is non-null - so might as well get rid of the checks.
