Subject: [PATCH 1/2] mmc: mediatek: Fix module autoload
Date: Mon, 17 Oct 2016 13:13:44 -0300 [thread overview]
Message-ID: <1476720825-30442-1-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/mmc/host/mtk-sd.ko | grep alias
$
After this patch:
$ modinfo drivers/mmc/host/mtk-sd.ko | grep alias
alias: of:N*T*Cmediatek,mt8135-mmcC*
alias: of:N*T*Cmediatek,mt8135-mmc
