Subject[PATCH 1/9] pinctrl: pinctrl-nomadik: Fix possible memory leak
Date
If the Nomadik Pin Control driver is continuously bound and unbound
from the same device a number of times the kzalloc() will leak
memory. Replacing it with devm_kzalloc() will ensure memory is
freed automatically in the event of failure and unbinding.
