Subject: tty: serial: msm: Fix module autoload
From: Javier Martinez Canillas <javier@osg.samsung.com>
commit abe81f3b8ed2996e1712d26d38ff6b73f582c616 upstream.
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/tty/serial/msm_serial.ko | grep alias
$
After this patch:
$ modinfo drivers/tty/serial/msm_serial.ko | grep alias
alias: of:N*T*Cqcom,msm-uartdmC*
alias: of:N*T*Cqcom,msm-uartdm
alias: of:N*T*Cqcom,msm-uartC*
alias: of:N*T*Cqcom,msm-uart
