From ae97fec3701a559929c3529e35417fab133a4d39 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Tue, 17 Jul 2007 01:08:29 -0400 Subject: [PATCH] drivers/usb/misc/auerswald: fix status check, remove redundant check 1) We should only set 'actual_length' output variable if usb length is known to be good. 2) No need to check actual_length for NULL. The only caller always passes non-NULL value.
