From 611a485b5fac3a6dce32a1ae6ddd3e0df215aecd Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 22 May 2013 13:20:14 +0300 Subject: gpio-langwell: drop away explicit casting Since the type of the reg_base member is void __iomem * we don't need to have explicit casting in gpio_reg() and gpio_reg_2bit(). Update year in the copyright notice as well.
