From 678ea28b7c3cc9a7196192dc77dfc13513db3d5f Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 16 Mar 2014 19:38:25 +0000 Subject: [PATCH] ARM: l2c: remove old .set_debug method We no longer need or require the .set_debug method; we handle everything it used to do via the .write_sec method instead.
