From 61d793bbfb76ea6740dd1c1a4f2cdac57a0c1c5c Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Thu, 7 Mar 2013 10:48:19 +0200 Subject: gpio/gpio-ich: make ichx_gpio_check_available() return a pure boolean value It is more readable for humans to use double-bang (!!) to convert the value to pure boolean before it is returned.
