Subject: [media] blackfin: check devm_pinctrl_get() for errors

From: Dan Carpenter <dan.carpenter@oracle.com>

commit c9205e18b41a6ef5ad73e1c4b86a78b2ea3ccb9b upstream.

devm_pinctrl_get() can fail so we should check for that.

Fixes: 0a6824bc10de ('[media] v4l2: blackfin: select proper pinctrl state in ppi_set_params if CONFIG_PINCTRL is enabled')
