From 2c7c9630db45129838ed09f0ada718b0ac222377 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 10 Dec 2019 15:26:00 +0100 Subject: [PATCH] ASoC: siu_pcm: Use managed buffer allocation Clean up the driver with the new managed buffer allocation API. The hw_params and hw_free callbacks became superfluous (the rest were only debug prints) and got dropped.
