Subject: [PATCH 4/9] riscv: Change check_unaligned_access_speed_all_cpus to void
Date: Fri, 7 Feb 2025 17:19:44 +0100 [thread overview]
Message-ID: <20250207161939.46139-15-ajones@ventanamicro.com> (raw)
In-Reply-To: <20250207161939.46139-11-ajones@ventanamicro.com>
The return value of check_unaligned_access_speed_all_cpus() is always
zero, so make the function void so we don't need to concern ourselves
with it. The change also allows us to tidy up
check_unaligned_access_all_cpus() a bit.
