Subject: [PATCH v2 03/13] crypto: s390 - drop redundant dependencies on S390
Date: Sun, 20 Apr 2025 12:25:59 -0700	[thread overview]
Message-ID: <20250420192609.295075-4-ebiggers@kernel.org> (raw)
In-Reply-To: <20250420192609.295075-1-ebiggers@kernel.org>

From: Eric Biggers <ebiggers@google.com>

arch/s390/crypto/Kconfig is sourced only when CONFIG_S390=y, so there is
no need for the symbols defined inside it to depend on S390.
