From 080de5ba390c54b7504c43b36ae21911acf66b30 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Tue, 17 Mar 2015 08:39:01 +0800 Subject: [PATCH] phy: stih41x-usb: Fixup stih41x_usb_phy_power_on failure path If stih41x_usb_phy_power_on() fails, we need to call clk_disable_unprepare() before return error. This is to ensure we have balanced clk_enable/disable calls.
