commit e2bf801ecd4e62222a46d1ba9e57e710171d29c1 upstream.
Include the OF-based modalias in the uevent sent when registering devices on the sunxi RSB bus, so that user space has a chance to autoload the kernel module for the device.
Fixes a regression caused by commit 3f241bfa60bd ("arm64: allwinner: a64: pine64: Use dcdc1 regulator for mmc0"). When the axp20x-rsb module for the AXP803 PMIC is built as a module, it is not loaded and the system ends up with an disfunctional MMC controller.
