From 231543206452f5c42bace54b5c13dfe5a0313812 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Wed, 17 Mar 2010 23:05:57 +0100 Subject: USB: serial: generalise generic read implementation Add process_read_urb to usb_serial_driver so that a driver can rely on the generic read (and throttle) mechanism but still do device specific processing of incoming data (such as adding tty_flags before pushing to line discipline). The default generic implementation handles sysrq for consoles but otherwise simply pushes to tty.
