From fb56eb73c6266164e4b06c9eca9716348420dbf1 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Wed, 12 Jun 2019 17:44:10 +0900 Subject: [PATCH] ALSA: fireworks: code refactoring for pcm.hw_params/hw_free Two sets of callbacks for pcm.hw_params/hw_free but they have the same codes. This commit unifies each of the callbacks.
