Subject: ALSA: Re-export snd_pcm_format_name() function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6e5265ec34d3b9578973841ddec8b925e986136a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ALSA: Re-export snd_pcm_format_name() function

Re-export snd_pcm_format_name() function to be used outside the PCM core.
As a first example, usbaudio is changed to use it now again.
