From: Javier Martinez Canillas javier@osg.samsung.com
[ 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
