Subject: [PATCH 6/8] ARM: pxa: Use gpio arrays in vpac270_pcmcia driver
Date: Sat, 15 Jan 2011 19:25:56 +0100	[thread overview]
Message-ID: <1295115958-4811-6-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.
