Subject: [PATCH] soc_button_array: fix a crash during rmmod
Date: Tue, 22 Apr 2014 14:38:39 +0800 [thread overview]
Message-ID: <53560E6F.9000806@linux.intel.com> (raw)
In-Reply-To: <53560DD1.5050805@linux.intel.com>
When the system has zero or one button available, trying to rmmod
soc_button_array will cause crash. Fix this by properly handling -ENODEV
in probe().
