[PATCH 1/2] mfd: fsl-imx25-tsadc: Fix module autoload when registered via OF
From: Javier Martinez Canillas
Date: Fri Oct 14 2016 - 11:41:17 EST
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/mfd/fsl-imx25-tsadc.ko | grep alias
alias: platform:mx25-tsadc
After this patch:
$ modinfo drivers/mfd/fsl-imx25-tsadc.ko | grep alias
alias: platform:mx25-tsadc
alias: of:N*T*Cfsl,imx25-tsadcC*
alias: of:N*T*Cfsl,imx25-tsadc
