Subject: tty: serial: msm: Fix module autoload
From: Javier Martinez Canillas <[email protected]>
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
