Subject: pinctrl: sx150x: Add a static gpio/pinctrl pin range mapping
From: Peter Rosin <peda@xxxxxxxxxx>
commit b930151e5b55a0e62a3aad06876de891ac980471 upstream.
Without such a range, gpiolib fails with -EPROBE_DEFER, pending the
addition of the range. So, without a range, gpiolib will keep
deferring indefinitely.
Fixes: 9e80f9064e73 ("pinctrl: Add SX150X GPIO Extender Pinctrl Driver")
Fixes: e10f72bf4b3e ("gpio: gpiolib: Generalise state persistence beyond sleep")
