[PATCH 1/5] ASoC: Make struct snd_soc_card's dapm_widgets and dapm_routes const

[Lars-Peter Clausen]

Those should not be modified (and are not) by the core code, so make them const.
This also makes them consistent with the same members of snd_soc_codec.

[PATCH 2/5] ASoC: Call snd_soc_new_widgets() after registering cards DAPM widgets

[Lars-Peter Clausen]

After registering new DAPM widgets nd_soc_new_widgets() must be called,
otherwise DAPM for those new widgets will not work.

snd_soc_new_widgets() is placed after the card late_probe call, so cards
can register new DAPM widgets in there.

There's already a call for this in post_component_init(), it just needs
to be moved later in the sequence now.

post_component_init() is called for each registered codec (and auxdev).
Since all the DAPM widgets are kept in one list now it probably makes sense to
traverse that list only once, when all components have been registered.
But snd_soc_dapm_new_widgets also calls dapm_power_widgets which operates on
the passed dapm_context, will it be without any effect on the DAPM context,
when it is called on a newly allocated context?

Otherwise I would say call snd_soc_dapm_new_widgets once for the cards
dapm_context and snd_soc_dapm_sync for each codec context.

Yup.

There's no point in repeatedly syncing - it may cause audible issues if
we power things off due to incomplete information.  If the sync isn't
propagating over the entire system we should fix that.

Ok. I'll add a snd_soc_dapm_init_widgets(struct snd_soc_card *card) which will
basically do what snd_soc_dapm_new_widgets does except for calling
dapm_power_widgets.

The dapm context is really only used to see if it is widget-less context. In
which case the event type is used to see whether it should be powered or not.
But I wonder if that shouldn't really be done for all widget less contexts.
Since widget-less contexts dev_power is not set to 0 at the beginning of
dapm_power_widgets and all dapm contexts are forced into the same power state,
effectively that cause a system with a widget-less context to be stuck in a
powered state.
Since right now the cards dapm context is almost always widget-less this would
affect almost all systems.
This is what happens on such a system:
Playback starts, codec is powered up, card dapm context is forced to on,
playback stops, codec is powered down but card context is still on and will
force the codec on again.

And it is also used for passing the update struct around. But is there any
reason as to why to pass as a member of the dapm context instead of as a simple
parameter for dapm_power_widgets()? If not I would like to change it to the latter.
