From 553a05b8821f5a6bc633e97187933e2157b2d291 Mon Sep 17 00:00:00 2001 From: Márton Németh Date: Mon, 22 Oct 2007 00:56:52 -0400 Subject: Input: i8042 - export i8042_command() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Export the i8042_command() function which manages the mutual exclusion with the help of the i8042_lock spinlock. This allows to access i8042 safely from other parts of the kernel.
