Subject: [PATCH 1/3] clocksource/drivers/arm_arch_timer_mmio: Prevent driver unbind
Date: Tue, 11 Nov 2025 16:32:24 +0100	[thread overview]
Message-ID: <20251111153226.579-2-johan@kernel.org> (raw)
In-Reply-To: <20251111153226.579-1-johan@kernel.org>

Clockevents cannot be deregistered so suppress the bind attributes to
prevent the driver from being unbound and releasing the underlying
resources after registration.

Fixes: 4891f01527bb ("clocksource/drivers/arm_arch_timer: Add standalone MMIO driver")
Signed-off-by: Johan Hovold <johan@kernel.org>
