Subject: [PATCHv2 3/5] net: rfkill: gpio: remove gpio names
Date: Tue, 25 Feb 2014 14:22:28 +0200 [thread overview]
Message-ID: <1393330950-7283-4-git-send-email-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <1393330950-7283-1-git-send-email-heikki.krogerus@linux.intel.com>
There is no use for them in this driver. This will fix a
static checker warning..
net/rfkill/rfkill-gpio.c:144 rfkill_gpio_probe()
warn: variable dereferenced before check 'rfkill->name'
This will also make sure that when DT support is added,
"gpios" property can be used as no con_id labels are
provided.
