From 99d17cfa3bbc6f4edb175f819af59c6b9e245e82 Mon Sep 17 00:00:00 2001 From: Fabio Baltieri Date: Mon, 7 Jan 2013 17:47:41 +0100 Subject: [PATCH] usb: musb: ux500: use clk_prepare_enable and clk_disable_unprepare This patch converts the module to use clk_prepare_enable and clk_disable_unprepare variants as required by common clock framework. Without this the system crash during probe function.
