Thanks! >> >> Why to prevent using the console of the driver is built as module? > >I meant "if the driver is built as module" [Lu Jingchang-B35083] From your patch of " serial: imx: Allow module build", I think the code between #ifdef CONFIG_SERIAL_IMX_CONSOLE ... #else in imx.c won't be built because the configuration is CONFIG_SERIAL_IMX_CONSOLE_MODULE now. So it is the same as if disable CONFIG_SERIAL_IMX_CONSOLE when built the driver as a module, isn't it? On other hand, if enable CONFIG_SERIAL_X_CONSOLE option when the driver is configured as module, the build will fail with message like ERROR: "uart_console_device" [drivers/tty/serial/**.ko] undefined! Stephen Rothwel gives the solution once at url: http://www.linuxhorizon.com/9-linux/42b33a65f64d95a2.htm I have checked drivers/tty/serial/Kconfig to make sure that other serial drivers indeed did this way.
