Subject: [PATCH v3] pxa/mioa701: use gpio arrays for global and gsm gpio initialization

From: [email-masked] (Philipp Zabel)
Date: Thu, 28 Apr 2011 22:19:32 +0200

gpio_request_array() / gpio_free_array() are functional replacements for
mio_gpio_request() / mio_gpio_free(), which are now obsolete.
