Message-Id: <20251222-cc-can-link-sparc-v1-1-1823e4f49480@linutronix.de> Date: Mon, 22 Dec 2025 09:29:15 +0100 From: Thomas Weißschuh <thomas.weissschuh@...utronix.de> To: "David S. Miller" <davem@...emloft.net>, Andreas Larsson <andreas@...sler.com> Cc: sparclinux@...r.kernel.org, linux-kernel@...r.kernel.org, Thomas Weißschuh <thomas.weissschuh@...utronix.de> Subject: [PATCH] sparc: Implement ARCH_HAS_CC_CAN_LINK The generic CC_CAN_LINK detection does not work for all architectures. Make the logic easier to understand and allow the simplification of the generic CC_CAN_LINK by using a tailored implementation.
