From 9680b60ed79edaf52f84b65cbb20859bbb26cb68 Mon Sep 17 00:00:00 2001 From: Torsten Fleischer Date: Sun, 26 Oct 2014 19:33:13 +0800 Subject: [PATCH] usb: chipidea: Fix oops when removing the ci_hdrc module The call of 'kfree(ci->hw_bank.regmap)' in ci_hdrc_remove() sometimes causes a kernel oops when removing the ci_hdrc module. Since there is no separate memory allocated for the ci->hw_bank.regmap array, there is no need to free it.
