From 79608555aad77cd41e421bab41cc125b24e2d0c9 Mon Sep 17 00:00:00 2001 From: Luca Niccoli Date: Fri, 16 Oct 2009 22:22:47 +0200 Subject: [PATCH] eeepc-laptop: don't enable camera at startup if it's already on. Switching the camera takes 500ms, checking if it's on is almost free... The BIOS remembers the setting through reboots, so there's good chance the camera is already enabled.
