X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=747d3f1a8a2fc4d8447c63205421a6a67f22799b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Bluetooth: btqcomsmd: 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/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
