If anyone has any objections, please let me know. ------------------ From: Michael Walle [ Upstream commit 2ca42c3ad9ed875b136065b010753a4caaaa1d38 ] We can get rid of all the empty stubs because all these functions call of_property_read_variable_u{8,16,32,64}_array() which already have an empty stub if CONFIG_OF is not defined.
