Subject: [PATCH v3 11/13] crypto: hisilicon/sec2: Remove check of CONFIG_CPU_LITTLE_ENDIAN
Date: Fri, 18 Sep 2026 15:52:13 +0100	[thread overview]
Message-ID: <20260918145217.1669-12-will@kernel.org> (raw)
In-Reply-To: <20260918145217.1669-1-will@kernel.org>

The hisilicon "sec" driver targets arm64 but can be compile-tested on
other 64-bit architectures. In preparation for removing the definition
of CONFIG_CPU_LITTLE_ENDIAN for arm64 (since it will be little-endian
only), invert the check in sec_set_endian() so that it behaves as
little-endian by default.
