From 0bc1bd092af3c7c0b025ece93c3a86916f89f3ca Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Tue, 5 Jan 2021 13:02:38 +0100 Subject: tty_port: drop last traces of low_latency The main purpose of tty_port::low_latency was removed in commit a9c3f68f3cd8 (tty: Fix low_latency BUG) back in 2014. It was left in place for drivers as an optional tune knob. But only one driver has been using it until the previous commit. So remove this misconcept completely, given there are no users.
