+description:
+  The APBridge dummy codec is part of the Greybus audio framework,
+  used in Project Ara modular phone hardware. It provides a dummy
+  ALSA SoC codec driver for the APBridge audio interface, enabling
+  audio streaming between Greybus modules and the host processor
+  via the APBridge protocol.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.
