From fd01a7a1bf6722e32efa679f15507148784af1f7 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Thu, 22 Sep 2011 20:33:13 -0500 Subject: [PATCH] drivers/tty: don't use the byte channel handle as a parameter in ehv_bytechan.c The ePAPR hypervisor byte channel console driver only supports one byte channel as a console, and the byte channel handle is stored in a global variable. It doesn't make any sense to pass that handle as a parameter to the console functions, since these functions already have access to the global variable.
