[alsa-devel] [PATCH v2 03/13] ASoC: Intel - do not describe I/O configuration in the long card name

[Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>]

From: Jaroslav Kysela <perex@perex.cz>

The long card name might be used in GUI. This information should be hidden.

Add CONFIG_SND_SOC_INTEL_USER_FRIENDLY_LONG_NAMES configuration option.

+	  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.
