hso: remove setting of low_latency flag
This patch removes the setting of the low_latency flag. tty_flip_buffer_push() is occasionally being called in irq context, which causes a hang if the low_latency flag is set. Removing the low_latency flag only seems to impact the flush to ldisc, which will now be put on a workqueue. Signed-off-by: Filip Aben <f.aben@option.com> Signed-off-by: David S.
