From: Takashi Iwai Date: Mon, 2 Mar 2015 22:22:59 +0000 (+0100) Subject: ALSA: hda - Move some codes up to hdac_bus struct X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d068ebc25e6e1360510ad8023fe7bca3dacd204e;p=linux-beck.git ALSA: hda - Move some codes up to hdac_bus struct A few basic codes for communicating over HD-audio bus are moved to struct hdac_bus now. It has only command and get_response ops in addition to the unsolicited event handling. Note that the codec-side tracing support is disabled temporarily during this transition due to the code shuffling. It will be re-enabled later once when all pieces are settled down.
