Remove low_latency flag setting from nozomi and mxser drivers
commit 4d8d4d251df8eaaa3dae71c8cfa7fbf4510d967d upstream [ cebbert@redhat.com: backport to 2.6.27 ] 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> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
