Just a tiny nitpick below.

There is a dedicated method to generically handle the PROBE_DEFER
error returned by functions like get(resource): dev_err_probe().
So here you'd just need to do:
- if (IS_ERR(gpio->rst)) {
- dev_err(gpio->dev, "Cannot get reset descriptor\n");
- return PTR_ERR(gpio->rst);
- }
+ if (IS_ERR(gpio->rst))
+ return dev_err_probe(gpio->dev, PTR_ERR(gpio->rst),
+ "Cannot get reset descriptor\n");
