spi: spi-axi: Fix module autoload
If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/spi/spi-axi-spi-engine.ko | grep alias $ After this patch: $ modinfo drivers/spi/spi-axi-spi-engine.ko | grep alias alias: of:N*T*Cadi,axi-spi-engine-1.00.aC* alias: of:N*T*Cadi,axi-spi-engine-1.00.a Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Mark Brown <broonie@kernel.org>
