From 2400a2bfbd0e912193fe3b077f492d4980141813 Mon Sep 17 00:00:00 2001 From: Oliver Neukum Date: Mon, 20 Apr 2009 17:28:53 +0200 Subject: USB: removal of tty->low_latency hack dating back to the old serial code This removes tty->low_latency from all USB serial drivers that push data into the tty layer at hard interrupt context. It's no longer needed and actually harmful.
