From f69c2861b05e29c69abed6aafe0cefd224d9d4db Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 13 Nov 2024 12:16:27 +0100 Subject: ALSA: pcm: Define snd_pcm_mmap_data_{open|close}() locally snd_pcm_mmap_data_open() and _close() are defined as inline functions in the public sound/pcm.h, but those are used only locally in pcm_native.c, hence they should be better placed there. Also, those are referred as callbacks, the useless inline is dropped.
