From abe81f3b8ed2996e1712d26d38ff6b73f582c616 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Mon, 2 Jan 2017 11:57:20 -0300 Subject: tty: serial: msm: Fix module autoload 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 Signed-off-by: Javier Martinez Canillas Acked-by: Bjorn Andersson Cc: stable Signed-off-by: Greg Kroah-Hartman --- drivers/tty/serial/msm_serial.c | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers') diff --git a/drivers/tty/serial/msm_serial.c b/drivers/tty/serial/msm_serial.c index 7312e7e01b7e..6788e7532dff 100644 --- a/drivers/tty/serial/msm_serial.c +++ b/drivers/tty/serial/msm_serial.c @@ -1809,6 +1809,7 @@ static const struct of_device_id msm_match_table[] = { { .compatible = "qcom,msm-uartdm" }, {} }; +MODULE_DEVICE_TABLE(of, msm_match_table); static struct platform_driver msm_platform_driver = { .remove = msm_serial_remove, -- cgit v1.2.3
