[PATCH] regulator: max8973: get rid of extra variable for gpio validity

From: Laxman Dewangan
Date: Wed Apr 08 2015 - 09:42:16 EST


To find that dvs-gpio is valid or not, gpio API gpio_is_valid()
can be directly used instead of intermediate variable.

Removing the extra variable and using the gpio_is_valid().
