8250: Fix lock warning (and possible crash)
Splitting the 8250 code back up to avoid a clash with the NR_IRQS removal patch introduced a last minute bug. Put back the additional needed lines for the old lock init Signed-off-by: Alan Cox <alan@redhat.com> [ Ingo also reports that this can cause a spontaneous reboot crash with certain configs, and sends in an identical patch ] Tested-by: Kamalesh Babulal <kamalesh@linux.vnet.ibm.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
