Charles Han 0a3392b020 gpio: grgpio: Add NULL check in grgpio_probe ...

[ Upstream commit 050b23d081da0f29474de043e9538c1f7a351b3b ]

devm_kasprintf() can return a NULL pointer on failure,but this
returned value in grgpio_probe is not checked.
Add NULL check in grgpio_probe, to handle kernel NULL
pointer dereference error.
