From 828cb4edd8074d35f814e03bee3e2ad8b7d8f64b Mon Sep 17 00:00:00 2001 From: "Subhransu S. Prusty" Date: Fri, 4 Mar 2016 19:59:50 +0530 Subject: [PATCH] ALSA: hda - chmap helper args modified to use generic hdac objs. Chmap helper arguments are modified to use either hdac_device object or hdac_chmap object instead of codec specific object. With this moving these APIs to core will be easier. Helper added to access a specific channel_allocation object instead of directly accessing. Signed-off-by: Subhransu S.
