From 182dde7c5d4cd9fcac007c0798c9906fc5ea6889 Mon Sep 17 00:00:00 2001 From: Shuah Khan Date: Thu, 11 Feb 2016 21:41:30 -0200 Subject: [PATCH] [media] media: au0828 change to use Managed Media Controller API Change au0828 to use Managed Media Controller API to share media device and coordinate creating/deleting the shared media device with the snd-usb-audio driver. The shared media device is created as device resource of the parent usb device of the two drivers. Populate media device model with USB Device product name instead of au0828 device board name. This change is necessary because, if the media device is registered by the snd-usb-audio driver first, and it doesn't know the au0828 board name.
