Subject: [PATCH AUTOSEL for 4.4 09/36] pinctrl: sunxi: Fix A80 interrupt pin
 bank

From: Andre Przywara <andre.przywara@....com>

[ Upstream commit 6ad4cc8d1ac483e0fd33f605fb2788b0ecf51ed4 ]

On the A80 the pins on port B can trigger interrupts, and those are
assigned to the second interrupt bank.
Having two pins assigned to the same interrupt bank/pin combination does
not look healthy (instead more like a copy&paste bug from pins PA14-PA16),
so fix the interrupt bank for pins PB14-PB16, which is actually 1.

I don't have any A80 board, so could not test this.
