Subject: [PATCH] drm/amdgpu: Fix signedness bug in sdma_v4_0_process_trap_irq()
Date: Sun, 28 Apr 2024 15:57:00 +0300 [thread overview]
Message-ID: <afb229a9-3f18-44cb-b305-5fbb2e1b4ee3@moroto.mountain> (raw)
The "instance" variable needs to be signed for the error handling to work.
Fixes: b34ddc71267a ("drm/amdgpu: add error handle to avoid out-of-bounds")
Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org>
