tty: serial: 8250_core: allow to overwrite & export serial8250_startup()
The OMAP version of the 8250 can actually use 1:1 serial8250_startup(). However it needs to be extended by a wake up irq which should to be requested & enabled at ->startup() time and disabled at ->shutdown() time. v2…v3: properly copy callbacks v1…v2: add shutdown callback Acked-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
