Subject: [ 143/175] gpio/omap: fix _set_gpio_irqenable implementation

3.3-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tarun Kanti DebBarma <tarun.kanti@...com>

commit 8276536cec38bc6bde30d0aa67716f22b9b9705a upstream.

This function should be capable of both enabling and disabling interrupts
based upon the *enable* parameter. Right now the function only enables
the interrupt and *enable* is not used at all. So add the interrupt
disable capability also using the parameter.
