Subject: [PATCH] proximity: vl53l0x: Make VDD regulator actually optional
Date: Tue, 14 Jun 2022 13:20:50 +0200	[thread overview]
Message-ID: <20220614112049.302278-1-luca.weiss@fairphone.com> (raw)

Contrary to what the naming might suggest, devm_regulator_get_optional
returns -ENODEV in case the regulator is not found which will trigger
probe error in this driver.

Use devm_regulator_get instead which will return a dummy regulator that
we can just use as if it was a proper regulator.

Fixes: d3d6dba56dab ("proximity: vl53l0x: Handle the VDD regulator")

@Jonathan: As discussed in the other email, maybe you want to
adjust/remove the "Fixes:" tag. Your call.
