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. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
