From 339f36ba14cf9f8fcf6e6b78385bd6811ec59fbe Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Sun, 8 Nov 2015 13:01:13 -0500 Subject: tty: Define tty_*() printk macros Since not all ttys are devices (eg., SysV ptys), dev_*() printk macros cannot be used. Define tty_*() printk macros that output in similar format to dev_*() macros (ie., : .....). Transform the most-trivial printk( LEVEL ...) usage to tty_*() usage. NB: The function name has been eliminated from messages with unique context, or prefixed to the format when given.
