SubjectRe: [Patch] um: fix a build error
I just ran across the same build error, does
something like this look reasonable? Only build
and boot tested.

This fixes the following build error:

CC arch/um/drivers/line.o
arch/um/drivers/line.c: In function ‘line_write_interrupt’:
arch/um/drivers/line.c:366: error: ‘struct tty_ldisc’ has no member
named ‘write_wakeup’
arch/um/drivers/line.c:367: error: ‘struct tty_ldisc’ has no member
named ‘write_wakeup’
make[1]: *** [arch/um/drivers/line.o] Error 1
make: *** [arch/um/drivers] Error 2
