From f6604efe0bee759f4db34757f2872b611288ef0f Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 23 Feb 2013 17:55:39 +0000 Subject: [PATCH] ARM: cleanup gate_vma initialization Three's no need to have code initializing this by hand; it's more efficient to initialize the constant structure members directly.
