hwrng: meson - Fix module autoload for OF registration
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/char/hw_random/meson-rng.ko | grep alias alias: platform:meson-rng After this patch: $ modinfo drivers/char/hw_random/meson-rng.ko | grep alias alias: platform:meson-rng alias: of:N*T*Camlogic,meson-rngC* alias: of:N*T*Camlogic,meson-rng Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Acked-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
