From: Thierry Reding <treding@xxxxxxxxxx>
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.
