[PATCH] pinctrl: single: check for any error when getting rows

From: Axel Haslam
Date: Wed Nov 09 2016 - 09:23:59 EST


pinctrl_count_index_with_args returns -ENOENT not
-EINVAL. The return check would pass, and we would
try to kzalloc with a negative error size throwing
a warning.

Instead of checking for -EINVAL specifically, lets
check for any error and avoid negative size allocations.
