[PATCH] Bluetooth: btqcomsmd: Fix module autoload

From: Javier Martinez Canillas
Date: Mon Jan 02 2017 - 08:10:25 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/bluetooth/btqcomsmd.ko | grep alias
$

After this patch:

$ modinfo drivers/bluetooth/btqcomsmd.ko | grep alias
alias: of:N*T*Cqcom,wcnss-btC*
alias: of:N*T*Cqcom,wcnss-bt
