Subject: [2.6 patch] drivers/input/serio/libps2.c: ps2_command: add a missing check
Date: Thu, 24 Mar 2005 04:14:47 +0100	[thread overview]
Message-ID: <20050324031447.GY1948@stusta.de> (raw)

The Coverity checker noted that while all other uses of param in 
ps2_command() were guarded by a NULL check, this one wasn't.
