[PATCH] devfreq: imx-bus: Use of_property_present()

From: Rob Herring (Arm)
Date: Wed Jul 31 2024 - 15:15:59 EST


Use of_property_present() to test for property presence rather than
of_get_property(). This is part of a larger effort to remove callers
of of_get_property() and similar functions. of_get_property() leaks
the DT property data pointer which is a problem for dynamically
allocated nodes which may be freed.
