Miller" <davem@...emloft.net> Cc: Arnd Bergmann <arnd@...db.de>, linux-arm-kernel@...s.com, linux-crypto@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] crypto: axis - hide an unused variable Without CONFIG_DEBUG_FS, we get a harmless warning: drivers/crypto/axis/artpec6_crypto.c:352:23: error: 'dbgfs_root' defined but not used [-Werror=unused-variable] This moves it into the #ifdef that hides the only user.
