From 4aeacd5bd5c354c1b36bfe3d5d72806ecd9605a0 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sat, 15 Dec 2012 23:50:53 +0100 Subject: [PATCH] sh-pfc: Use sh_pfc_ namespace prefix through the whole driver Most of the function and structure names are prefixed by sh_pfc_. Fix the ones that are not to avoid namespace clashes (especially for functions that start with gpio_). Not included in this patch are the platform data structures, those will be reworked later.
