Subject: [PATCH 3.16 334/366] ALSA: timer: Fix pause event notification

3.16.60-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Ben Hutchings <ben.hutchings@...ethink.co.uk>

commit 3ae180972564846e6d794e3615e1ab0a1e6c4ef9 upstream.

Commit f65e0d299807 ("ALSA: timer: Call notifier in the same spinlock")
combined the start/continue and stop/pause functions, and in doing so
changed the event code for the pause case to SNDRV_TIMER_EVENT_CONTINUE.
Change it back to SNDRV_TIMER_EVENT_PAUSE.

Fixes: f65e0d299807 ("ALSA: timer: Call notifier in the same spinlock")
