[4/5] ASoC: pxa: e800_wm9712: Introduce the use of devm_gpio_request_array

Commit Message

HIMANGI SARAOGI July 6, 2014, 5:51 p.m. UTC

This patch moves the resources allocated using gpio_request_array to the
managed interface and removes the calls to gpio_free_array in the probe
and remove functions.
