From 39f56b757cf9778572041f497f6fad890224c9fb Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 31 May 2018 00:00:35 +0200 Subject: [PATCH] ASoC: mediatek: export mtk-afe symbols as needed The new mt6797-afe driver uses some functions in a common file, which works for a built-in driver but fails for a loadable module: ERROR: "mtk_afe_pcm_free" [sound/soc/mediatek/mt6797/snd-soc-mt6797-afe.ko] undefined! ERROR: "mtk_afe_add_sub_dai_control" [sound/soc/mediatek/mt6797/snd-soc-mt6797-afe.ko] undefined! ERROR: "mtk_afe_pcm_new" [sound/soc/mediatek/mt6797/snd-soc-mt6797-afe.ko] undefined!
