From: Thierry Reding <redacted> This driver uses bus_find_device() to go through every platform device and match using the driver and device tree node. It's more efficient to use driver_find_device() to iterate over all devices associated with a particular driver, in which case the matching is reduced to the device tree node and can be done using the common implementation.
