| Subject: tty: serial: msm: Fix module autoload |
| |
| 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 |
