Stephen, it is my fault. qipan did a strange mis-operation when he
prepared this patch and i didn't double-confirm it.
but the patch did have been tested on real hardware to fix the
deadlock issue. it is not a patch without test.

the build issue has been fixed in another thread: [PATCH tty-next]
serial: sirf: Fix compilation failure
https://lkml.org/lkml/2014/5/29/476

i am very sorry for this as the related platform maintainer. i didn't
control this well and missed to do a double build for this. again, i
am very sorry!
