[PATCH 3.16 230/305] ALSA: control: fix failure to return numerical ID in 'add' event

[Ben Hutchings]

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

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

From: Takashi Sakamoto <o-takashi@xxxxxxxxxxxxx>

commit d34890cf4113397625a6629d71749fa638a7a734 upstream.

Currently when adding a new control, the assigned numerical ID is not
set for event data, thus userspace applications cannot realize it just
by event data.
