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. Fixes: a21eb94fc4d3 ("crypto: axis - add ARTPEC-6/7 crypto accelerator driver") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Lars Persson <larper@axis.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
