From
Subject[PATCH] of: __of_update_property_sysfs only call __of_sysfs_remove_bin_file if of_node_is_attached.
Date
To prevent warning "kernfs: can not remove '(null)', no directory", if an overlay isn't applied to the active devicetree.

Using of_remove_property and than of_add_property don't show the warning.
