Subject: [PATCH 10/10] microblaze: use built-in function to get CPU_{MAJOR,MINOR,REV}
Date: Mon, 13 Dec 2021 04:29:41 +0900 [thread overview]
Message-ID: <20211212192941.1149247-11-masahiroy@kernel.org> (raw)
In-Reply-To: <20211212192941.1149247-1-masahiroy@kernel.org>
Use built-in functions instead of shell commands to avoid forking
processes.
