This is a note to let you know that I've just added the patch titled
serial: sh-sci: Initialize spinlock for uart consoleto my tty git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git in the tty-linus branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
If you have any questions about this process, please let me know.
It looks like it's a regression in serial_core.c [1] as Geert pointed out [2]. Please drop this patch until we come to a conclusion.

We have had MANY patches for individual drivers to fix up the issue with that serial_core patch. I think, and hope, they are all now caught. If not, please let us know, but for now, this patch is needed, so I'll keep it.
thanks,
