Subject: [PATCH AUTOSEL 4.19 017/671] ASoC: wm9712: fix unused variable warning

From: Arnd Bergmann <arnd@...db.de>

[ Upstream commit 18380dcc52cc8965e5144ce33fdfad7e168679a5 ]

The 'ret' variable is now only used in an #ifdef, and causes a
warning if it is declared outside of that block:

sound/soc/codecs/wm9712.c: In function 'wm9712_soc_probe':
sound/soc/codecs/wm9712.c:641:6: error: unused variable 'ret' [-Werror=unused-variable]

Fixes: 2ed1a8e0ce8d ("ASoC: wm9712: add ac97 new bus support")
