From 922c88a8368a61ee93653d4a2888a7f4ce263102 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 17 Feb 2015 14:46:40 +0100 Subject: ALSA: hda - Embed struct hda_bus_unsolicited into struct hda_bus There is no big merit to handle hda_bus_unsolicited object individually, as it's tightly coupled with the hda_bus object itself. Embedding it makes the code simpler in the end.
