Subject: [PATCH v4 1/6] RISC-V: Make zicbom/zicboz errors consistent
Date: Mon, 18 Sep 2023 15:15:20 +0200	[thread overview]
Message-ID: <20230918131518.56803-9-ajones@ventanamicro.com> (raw)
In-Reply-To: <20230918131518.56803-8-ajones@ventanamicro.com>

commit c818fea83de4 ("riscv: say disabling zicbom if no or bad
riscv,cbom-block-size found") improved the error messages for
zicbom but zicboz was missed since its patches were in flight
at the same time. Get 'em now.
