From 8433a509c0eb6bb1f33ce39c82c580b8901619ee Mon Sep 17 00:00:00 2001 From: Nishanth Aravamudan Date: Mon, 24 Oct 2005 15:02:37 +0200 Subject: [ALSA] Fix schedule_timeout usage Use schedule_timeout_{,un}interruptible() instead of set_current_state()/schedule_timeout() to reduce kernel size. Also use human-time conversion functions instead of hard-coded division to avoid rounding issues.
