4.2.8-ckt3 -stable review patch. If anyone has any objections, please let me
know.

From: Stefan Wahren <stefan.wah...@i2se.com>
commit 53653c6b91750debba6dc4503003c851257fd340 upstream.
In case of an invalid pin value bcm2835_pctl_dt_node_to_map()
would leak the pull configs of already assigned pins.
So avoid this by calling the free map function in error case.
