Remove low_latency flag setting from nozomi and mxser drivers
The kernel oopses if this flag is set. [and neither driver should set it as they call tty_flip_buffer_push from IRQ paths so have always been buggy] Signed-off-by: Chuck Ebbert <cebbert@redhat.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
