[PATCH 4.7 036/141] gpio: sa1100: fix irq probing for ucb1x00

[Greg Kroah-Hartman]

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

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

From: Russell King <rmk+kernel@xxxxxxxxxxxxxxx>

commit 56beac95cb88c188d2a885825a5da131edb41fe3 upstream.

ucb1x00 has used IRQ probing since it's dawn to find the GPIO interrupt
that it's connected to.  However, commit 23393d49fb75 ("gpio: kill off
set_irq_flags usage") broke this by disabling IRQ probing on GPIO
interrupts.  Fix this.

Fixes: 23393d49fb75 ("gpio: kill off set_irq_flags usage")
