The patch titled
gpio: make gpio_{request,free}_array gpio array parameter const
has been removed from the -mm tree. Its filename was
gpio-make-gpio_requestfree_array-gpio-array-parameter-const.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: gpio: make gpio_{request,free}_array gpio array parameter const
From: Lars-Peter Clausen <lars@xxxxxxxxxx>
gpio_{request,free}_array should not (and do not) modify the passed gpio
array, so make the parameter const.
