[PATCH] iio: adc: aspeed: Use of_property_present()

From: Rob Herring (Arm)
Date: Wed Jul 31 2024 - 15:14:21 EST


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