From d86d01935a4c4c818514d8c23579703abd768329 Mon Sep 17 00:00:00 2001 From: Rene Herman Date: Tue, 18 Sep 2007 18:10:49 +0200 Subject: [ALSA] alsa-kernel: schedule_timeout() fixes Fix schedule_timeout() use in alsa-kernel. Mostly just schedule_timeout(1) --> schedule_timeout_uninterruptible(1) The wavefront_synth one fixes the surrounding loop as well. In ymfpci_main, delete a superfluous set_current_state() and in soc/soc-dapm.c replace an _interruptible with _uninterruptible in some debug code; it's not waiting for signals.
