Subject: [PULL 01/14] accel/nvmm: Fix NULL dereference in nvmm_init_vcpu()
Date: Fri,  3 May 2024 17:36:00 +0200	[thread overview]
Message-ID: <20240503153613.38709-2-philmd@linaro.org> (raw)
In-Reply-To: <20240503153613.38709-1-philmd@linaro.org>

When mechanically moving the @dirty field to AccelCPUState
in commit 79f1926b2d, we neglected cpu->accel is still NULL
when we want to dereference it.

Reported-by: Volker Rümelin <vr_qemu@t-online.de>
Suggested-by: Volker Rümelin <vr_qemu@t-online.de>
Fixes: 79f1926b2d ("accel/nvmm: Use accel-specific per-vcpu @dirty field")
Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
