Subject: [PATCH 3/8] ARM: pxa: Use gpio arrays in palmld_pcmcia driver
Date: Sat, 15 Jan 2011 19:25:53 +0100 [thread overview]
Message-ID: <1295115958-4811-3-git-send-email-marek.vasut@gmail.com> (raw)
In-Reply-To: <1295115958-4811-1-git-send-email-marek.vasut@gmail.com>
Use gpio_request_array() / gpio_free_array(), this makes the code
cleaner and less error prone.
