[PATCH] soc: ti: knav: Drop unnecessary check for property presence

From: Rob Herring (Arm)
Date: Wed Jul 31 2024 - 16:14:52 EST


of_property_read_u32() returns -EINVAL if a property is not present, so
the preceeding check for presence with of_get_property() can be
dropped.

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