Subject: scsi: ufs-qcom: Fix module autoload
From: Javier Martinez Canillas <javier@xxxxxxxxxxxxxxx>
[ Upstream commit ab3dabb3e8cf077850f20610f73a0def1fed10cb ]
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/scsi/ufs/ufs-qcom.ko | grep alias
$
After this patch:
$ modinfo drivers/scsi/ufs/ufs-qcom.ko | grep alias
alias: of:N*T*Cqcom,ufshcC*
alias: of:N*T*Cqcom,ufshc
