1) for projects with device specific modules, this property should only be set while device modules been loaded. 2) also remove "wait_for_prop vendor.device.modules.ready 1" to prevent infinite wait 3) migrate vendor.all.modules.ready/vendor.all.devices.ready to init.insmod.<DEVICE>.cfg and set these proprieties while .cfg not exist Bug: 238853979 Signed-off-by: Robin Peng <robinpeng@google.com> Change-Id: Ie5a2b939191947c4fce154dde48859a28fe86329
