From 1e63bc7342c40f0f1dd83d80d368665bd06f4963 Mon Sep 17 00:00:00 2001 From: Nishanth Aravamudan Date: Sat, 10 Sep 2005 00:27:31 -0700 Subject: [PATCH] [PATCH] telephony: fix-up schedule_timeout() usage Use schedule_timeout_uninterruptible() instead of set_current_state()/schedule_timeout() to reduce kernel size.
