Takashi Iwai 7378bc2f19 ALSA: jack: Fix endless loop at unique index detection
While the commit [d0a601c278de: ALSA: jack: Fix the id uniqueness
check] fixes the wrong string check, it leads to a worse result -- the
loop in get_available_index() goes into an endless loop.  The cause is
that snd_ctl_find_id() returns the object assigned to the numid if
it's set.  Thus it points to the previous entry again.

This patch clears the numid field for the next call properly.

Takashi Iwai d0a601c278 ALSA: jack: Fix the id uniqueness check
snd_kctl_jack_new() tries to assign a unique index number when a name
string that has been already registered is passed.  However, it checks
with the base string without "Jack" suffix, so it never hits.
Fix the call with the properly processed name string instead.

Jie Yang 807845e364 ALSA: jack: remove exporting ctljack functions
snd_kctl_jack_new() and snd_kctl_jack_report() are internal only now
so make them static.

Jie Yang 2ba2dfa1fc ALSA: hda - Update to use the new jack kctls method
Jack snd_kcontrols can now be created during snd_jack_new()
or by later calling snd_jack_add_new_kctls().

This patch creates the jacks during the initialisation stage
for both phantom and non phantom jacks.

Jie Yang b8dd086674 ALSA: Jack: handle jack embedded kcontrol creating within ctljack
This patch adds a static method get_available_index() to
allocate the index of new jack kcontrols and also adds
jack_kctl_name_gen() which is used to ensure compatibility
with jack naming by removing " Jack" from some incorrectly
passed names.

Takashi Iwai 35be544af3 ALSA: Introduce common helper functions for jack-detection control
Now move the helper function for creating and reporting the jack-detection
to the common place.  The driver that needs this functionality should
select CONFIG_SND_KCTL_JACK kconfig.
