Since the recent integration of kctl jack and input jack layers, we can basically build the jack layer even without input devices. That is, the jack layer itself can be built with conditional to enable the input device support or not, while the users may enable always CONFIG_SND_JACK unconditionally. For achieving it, this patch changes the following: - A new Kconfig, CONFIG_SND_JACK_INPUT_DEV, was introduced to indicate whether the jack layer supports the input device, - A few items in snd_jack struct and relevant codes are conditionally built upon CONFIG_SND_JACK_INPUT_DEV, - The users of CONFIG_SND_JACK drop the messy dependency on CONFIG_INPUT. This change also automagically fixes a potential bug in HD-audio driver Arnd reported, where the NULL or uninitialized jack instance is dereferenced.

If you want ASoC support, you should say Y here and also to the
|
|
specific driver for your SoC platform below.
|
|
|
|
ASoC provides power efficient ALSA support for embedded battery powered
|
|
SoC based systems like PDA's, Phones and Personal Media Players.
|
|
|
|
This ASoC audio support can also be built as a module. If so, the module
|
|
will be called snd-soc-core.
