Subject: [PATCH next] drm/amdkfd: Fix kfd_smi_event_process()
Date: Tue, 15 Apr 2025 13:44:50 +0300 [thread overview]
Message-ID: <Z_44oq-aSZOsvxTN@stanley.mountain> (raw)
The "pdd->drm_priv" NULL check is reversed so it will lead to a NULL
dereference on the next line.
Fixes: 4172b556fd5b ("drm/amdkfd: add smi events for process start and end")
Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org>
