spi: add of_device_uevent_modalias support
Add OF support as already done for ACPI to take driver MODULE_DEVICE_TABLE(of, ..) into account. For example with this change a spi nor device MODALIAS changes from: MODALIAS=spi:spi-nor to MODALIAS=of:Nspi-flashT(null)Cjedec,spi-nor Signed-off-by: Marco Felsch <m.felsch@pengutronix.de> Link: https://lore.kernel.org/r/20210525091003.18228-1-m.felsch@pengutronix.de Signed-off-by: Mark Brown <broonie@kernel.org>
