5.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Rob Herring <robh@xxxxxxxxxx> [ Upstream commit 9cbad37ce8122de32a1529e394b468bc101c9e7f ] Add an of_property_present() function similar to fwnode_property_present(). of_property_read_bool() could be used directly, but it is cleaner to not use it on non-boolean properties.
