From b3cacf318172757783d8272fc333284dd4f50140 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Thu, 7 May 2009 10:31:39 +0000 Subject: [PATCH] sh: call clock framework init() callback once Make sure that clk->ops->init() only gets called once in the case of CLK_ALWAYS_ENABLED. Without this patch the init() callback may be called multiple times.
