usb: chipidea: Fix oops when removing the ci_hdrc module

9680b60e · Torsten Fleischer <[email protected]> · 2014-10-26 19:33:13 +08:00

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.
