[PATCH 3/4] spi: xlp: Fix module autoload for OF registration

From: Javier Martinez Canillas
Date: Wed Nov 23 2016 - 11:37:54 EST


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-xlp.ko | grep alias
alias: acpi*:BRCM900D:*

After this patch:

$ modinfo drivers/spi/spi-xlp.ko | grep alias
alias: acpi*:BRCM900D:*
alias: of:N*T*Cnetlogic,xlp832-spiC*
alias: of:N*T*Cnetlogic,xlp832-spi
