From 504dc9f5e62e3beef2554c453576e84993053647 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 7 Aug 2024 15:34:44 +0200 Subject: [PATCH] ALSA: core: Drop snd_print stuff and co Now that all users of snd_print*() are gone, let's drop the functions completely. This also makes CONFIG_SND_VERBOSE_PRINTK redundant, and it's dropped, too.
