From 830e7b0076814a414ab96ac555cfdd5247e6f568 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:48:59 +0100 Subject: ALSA: azt3328: Use managed buffer allocation Clean up the driver with the new managed buffer allocation API. The hw_params and hw_free callbacks became superfluous and got dropped.
