Subject: [PATCH] scsi: ufs-qcom: Fix module autoload
Date: Mon, 2 Jan 2017 11:04:58 -0300 [thread overview]
Message-ID: <1483365898-30166-1-git-send-email-javier@osg.samsung.com> (raw)
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
