We have helper routines to lookup devices matching a criteria defined
by a "match" helper for bus/class/driver. Often the search is based on a
generic property of a device, such as of_node, fwnode, device type or
device name. In the absense of a common set of match functions, we have
drivers writing their own match functions, spilled all over the driver
subsystems. This series is an attempt to consolidate the and cleanup
the device match functions by providing generic match helpers by device
properties listed above. In this attempt, we unify the prototype for
the match functions for {bus/driver}_find_device() with that of the
class_find_device() and thus further reducing the duplicate functions.
The series also adds wrapper functions to lookup the devices by generic
attributes, so that people don't miss the generic match functions and
continue to write their own.Also, there are a couple of instances where the drivers use "platform_bus_type" directly reusing the "match" function of the bus. This is cleaned by providing a new helper "platform_find_device_by_driver()" to abstract the details away from the callers.
