Subject: [PATCH v4 15/28] arm64/sysreg: Standardise naming for SSBS feature enumeration
Date: Thu, 18 Aug 2022 13:24:12 +0100	[thread overview]
Message-ID: <20220818122425.37889-16-broonie@kernel.org> (raw)
In-Reply-To: <20220818122425.37889-1-broonie@kernel.org>

In preparation for conversion to automatic generation refresh the names
given to the items in the SSBS feature enumeration to reflect our standard
pattern for naming, corresponding to the architecture feature names they
reflect. No functional change.
