Subject: [PATCH 01/25] twl4030: fix potential null pointer dereference
Date: Tue, 30 Sep 2008 21:42:45 +0300 [thread overview]
Message-ID: <1222800189-29737-2-git-send-email-me@felipebalbi.com> (raw)
In-Reply-To: <1222800189-29737-1-git-send-email-me@felipebalbi.com>
From: Felipe Balbi <felipe.balbi@nokia.com>
The following patch fix a potential null pointer
dereference in twl4030 keypad driver when parts
of keypad platform_data aren't passed down to the
driver. At that point kp->dbg_dev is not set yet.
