Subject: [PATCH] pinctrl-bcm2835: Fix cut-and-paste error in "pull" parsing

From: Phil Elwell <phil@...pberrypi.org>

The DT bindings for pinctrl-bcm2835 allow both the function and pull
to contain either one entry or one per pin. However, an error in the
DT parsing can cause failures if the number of pulls differs from the
number of functions.

Yes, the s-o-b differs from the author of the commit, but this falls
under part b) of the process.

Phil, any chance you could start putting Signed-off-by lines on your
kernel commits?
