| Subject: usb: chipidea: Fix oops when removing the ci_hdrc module |
| |
| From: Torsten Fleischer <to-fleischer@t-online.de> |
| |
| commit 9680b60ed79edaf52f84b65cbb20859bbb26cb68 upstream. |
| |
| 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. |
