From d708c2b36b5d23a7266ca9bfe648533a0f61bdfd Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 10 Dec 2019 15:26:01 +0100 Subject: [PATCH] ASoC: generic-dmaengine-pcm: Use managed buffer allocation Clean up the driver with the new managed buffer allocation API. The hw_free callback became superfluous and got dropped.
