From f4b1e98aa93d548e5d51c8c5272ea08562fc71c1 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Fri, 17 Jun 2011 08:17:56 +0200 Subject: ALSA: firewire-speakers, oxygen, ua101: allow > 10 s periods Since commit f2b3614cefb6 (Don't check DMA time-out too shortly), drivers need no longer restrict their PCM period length to be shorter than 10 seconds.
