serial: export fsl8250_handle_irq

arndb · gregkh · commit bd63acf9e9a6 · 2015-11-20T16:19:54.000-08:00
fsl8250_handle_irq is now used by the of_serial driver, and that fails if it is a loadable module: ERROR: "fsl8250_handle_irq" [drivers/tty/serial/of_serial.ko] undefined! This exports the symbol to avoid randconfig errors.
