[alsa-devel] [PATCH v2 1/3] ASoC: add control components management
This ASCII string can carry additional information about soundcard components or configuration. Add the possibility to set this string via the ASoC card.

Use the control interface (field 'components' in the info structure) to pass the I/O configuration details. The goal is to replace the card long name with this.

Please, remove this extra new line when you apply the patch.
Thanks, Jaroslav
The long card name might be used in GUI. This information should be hidden.
Add CONFIG_SND_SOC_INTEL_USER_FRIENDLY_NAMES configuration option.

Some drivers might pass the I/O configuration through thesoundcard's driver name in the control user space API. It maybe used in GUI. If you do not like this and the user spacedoes not depend on this (like UCM - Use Case Manager),then select "Y".
Sorry for being picky here, but I find the wording confusing with two negatives resulting in a Y.
maybe
Some drivers report the I/O configuration to userspace through the soundcard's long card name in the control user space AP. An unfortunate side effect is that this long name may also be used by the GUI, confusing users with information they don't need. This option prevents the long name from being modified, and the I/O configuration will be provided through a different component interface. Select Y if userspace like UCM (Use Case Manager) uses the component interface. If unsure select N.

Thanks, I used your text. The v3 patches are sent without the first one which is already merged to the Mark's tree.
Thanks for review, Jaroslav
