4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Javier Martinez Canillas <javier@xxxxxxxxxxxxxxx>
[ Upstream commit 8f0d7daf53972da0004f7a5a4d938c85333db300 ]
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/iio/adc/fsl-imx25-gcq.ko | grep alias
$
After this patch:
$ modinfo drivers/iio/adc/fsl-imx25-gcq.ko | grep alias
alias: of:N*T*Cfsl,imx25-gcqC*
alias: of:N*T*Cfsl,imx25-gcq
