Subject: [PATCH v2 06/13] RISC-V: kprobes: use central defined funct3 constants
Date: Mon, 28 Nov 2022 11:26:25 +0100	[thread overview]
Message-ID: <20221128102632.435174-7-heiko@sntech.de> (raw)
In-Reply-To: <20221128102632.435174-1-heiko@sntech.de>

From: Heiko Stuebner <heiko.stuebner@vrull.eu>

Don't redefine values that are already available in a central header.
Use the central ones instead.
