From 7a6f8416e22a6d9f4708847bb2d88f0719b0f49e Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Fri, 22 Apr 2011 08:15:46 -0700 Subject: [PATCH] gpio/omap: remove useless gpio_valid() & check_gpio() checks These functions are useless. They are only called in a few places, and where they are called, the GPIO has already been converted from an IRQ or masked, so these functions will never fail.
