From 7802fb52564b5d6b4fdcf25a08d487897f9e4a8b Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Fri, 9 Jun 2017 09:34:40 +0900 Subject: [PATCH] ALSA: pcm: move fixup of info flag after selecting single parameters When drivers register no flags about information of PCM hardware, ALSA PCM core fixups it roughly. Currently, this operation places in a function snd_pcm_hw_refine(). It can be moved to a function fixup_unreferenced_params() because it doesn't affects operations between these two functions. This idea is better to bundle codes with similar purposes and this commit achieves it.
