[2/5] ASoC: wm1250-ev1: Use devm_gpio_request_array

Commit Message

HIMANGI SARAOGI July 6, 2014, 5:48 p.m. UTC

This patch replaces a call to the unmanaged function
gpio_request_array by a call to the managed function
devm_gpio_request_array and removes the calls to gpio_free_array
in wm1250_ev1_pdata, which is called by the probe function. The
function wm1250_ev1_free is no longer needed and is removed.
