[PATCH] crypto: axis - hide an unused variable

From: Arnd Bergmann
Date: Wed Sep 06 2017 - 09:11:17 EST


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")

Originally sent on August 25, but hasn't made it into linux-next
yet. Resending it in case it got lost, sorry for any duplicates
if this was still pending.
