[PATCH] regulator: pwm-regulator: Make use of the helper function dev_err_probe()

From: Anand Moon
Date: Sun Sep 19 2021 - 17:12:07 EST


devm_regulator_register can return -EPROBE_DEFER if the
regulator is not ready yet. Use dev_err_probe() for
pwm regulator resources to indicate the deferral reason
when waiting for the resource to come up.

Fixes: 0cd71b9a43ad ("regulator: pwm: Don't warn on probe deferral")
