From 441c2440aba2efd8d0f48a5e3357deec92283d62 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Tue, 11 May 2010 09:37:12 +0000 Subject: [PATCH] sh: remove unused clock lookup Now when all clocks are registered using clkdev, get rid of the special SH-specific clock lookup. Also ditch the unused module ref counting code. This patch syncs the SH behaviour with ARM.
