Wysocki" , linux-arm-kernel@lists.infradead.org, Dmitry Torokhov , devicetree@vger.kernel.org, Linus Walleij , linux-acpi@vger.kernel.org, Arnd Bergmann , Tomeu Vizoso , Liam Girdwood List-Id: devicetree@vger.kernel.org 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.
