Subject: [PATCH 10/53] ALSA: x86: Call event callback directly
Date: Thu, 2 Feb 2017 18:02:24 +0100 [thread overview]
Message-ID: <20170202170307.24484-12-tiwai@suse.de> (raw)
In-Reply-To: <20170202170307.24484-1-tiwai@suse.de>
Currently the driver calls the event callback stored in its ctx
pointer, but it's obviously inefficient. Replace it with the direct
calls.
