Subject: [RFC 1/9] RISC-V: Fix the typo in Scountovf CSR name
Date: Mon,  4 Dec 2023 18:43:02 -0800	[thread overview]
Message-ID: <20231205024310.1593100-2-atishp@rivosinc.com> (raw)
In-Reply-To: <20231205024310.1593100-1-atishp@rivosinc.com>

The counter overflow CSR name is "scountovf" not "sscountovf".

Fix the csr name.

Fixes: 4905ec2fb7e6 ("RISC-V: Add sscofpmf extension support")
