    Subject[PATCH v3 06/18] regulator: core: Probe regulators on demand
    Date
    When looking up a regulator through its OF node, probe it if it hasn't
    already.

    The goal is to reduce deferred probes to a minimum, as it makes it very
    cumbersome to find out why a device failed to probe, and can introduce
    very big delays in when a critical device is probed.
