Message-ID: <20250420192609.295075-4-ebiggers@kernel.org> Date: Sun, 20 Apr 2025 12:25:59 -0700 From: Eric Biggers <ebiggers@...nel.org> To: linux-crypto@...r.kernel.org Cc: linux-arch@...r.kernel.org, linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-mips@...r.kernel.org, linuxppc-dev@...ts.ozlabs.org, linux-riscv@...ts.infradead.org, linux-s390@...r.kernel.org, x86@...nel.org, "Jason A . Donenfeld" <Jason@...c4.com>, Ard Biesheuvel <ardb@...nel.org> Subject: [PATCH v2 03/13] crypto: s390 - drop redundant dependencies on S390 From: Eric Biggers <ebiggers@...gle.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.
