3.16.7-ckt1 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Torsten Fleischer <to-fleischer at 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.
