3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Boris BREZILLON <b.brezil...@overkiz.com>
commit 05d3534a321d7fe4524b3b83bb20318282f3ec2c upstream.
In PIO_PUSR and PIO_PPDSR register if a given bit is set 1 this means the
pullup/down for this pin (pin is represented as a bit position) is
disabled.
