Subject: [PATCH v2 1/5] riscv: cleanup svpbmt cpufeature probing
Date: Mon, 5 Sep 2022 13:10:23 +0200 [thread overview]
Message-ID: <20220905111027.2463297-2-heiko@sntech.de> (raw)
In-Reply-To: <20220905111027.2463297-1-heiko@sntech.de>
For better readability (and compile time coverage) use IS_ENABLED
instead of ifdef and drop the new unneeded switch statement.
