From 76f56fae1cf9040325a58d1375291baf71dfaf03 Mon Sep 17 00:00:00 2001 From: Rakesh Ughreja Date: Fri, 1 Jun 2018 22:53:50 -0500 Subject: [PATCH] ALSA: hdac: Remove usage of struct hdac_ext_bus and use hdac_bus instead This patch removes the hdac_ext_bus structure. The legacy and enhanced HDaudio capabilities can be handled in a backward-compatible way without separate definitions. Follow-up patches in this series handle the driver definition.
