Subject[PATCH 4.19 146/219] crypto: atmel - Fix authenc support when it is set to m
Date
From: Herbert Xu <herbert@gondor.apana.org.au>

[ Upstream commit 1520c72596dde7f22b8bd6bed3ef7df2b8b7ef39 ]

As it is if CONFIG_CRYPTO_DEV_ATMEL_AUTHENC is set to m it is in
effect disabled. This patch fixes it by using IS_ENABLED instead
of ifdef.

Fixes: 89a82ef87e01 ("crypto: atmel-authenc - add support to...")
