Re: [PATCH] regulator: rt4801: Fix NULL pointer dereference if priv->enable_gpios is NULL

[cy_huang(黃啟原)]

Hi, Axel:

Which case will cause this error? I'm not really sure.
But if devm_gpiod_get_array_optional will return null, then it must be check
earlier in probe function

        priv->enable_gpios = devm_gpiod_get_array_optional(&i2c->dev, "enable",
GPIOD_OUT_HIGH);
-       if (IS_ERR(priv->enable_gpios)) {+       if (IS_ERR_OR_NULL(priv->enable_gpios)) {

If so, this change will be more reasonable.
Cause in binding document, I already write the min item must be '1'.
