With the commit 4fcba5d556b4 ("regulator: implement basic reference counter") the return value of regulator_set_enable may be EALREADY or EBUSY for fixed/gpio regulators.
Change to use the more relaxed regulator_set_enable_if_allowed to continue if regulator already was enabled or disabled.
Sigh, can you please send series per-subsystem, so respective maintainers can pick the whole series relevant to the subsystem ? If it wasn't for Tom, I would've missed this patch entirely, since I only saw 1/5 which was some ADC patch I have no interest in.

Is this going to work if priv->vbus_supply is NULL ? (I think it won't work, so you need to re-add the check)
