Date: Wed, 22 Oct 2025 14:03:48 +0300	[thread overview]
Message-ID: <aPi6FB3E-LNbVYQB@stanley.mountain> (raw)

Hello YiPeng Chai,

Commit 13c91b5b4378 ("drm/amd/ras: Add rascore unified interface
function") from Mar 17, 2025 (linux-next), leads to the following
Smatch static checker warning:

	drivers/gpu/drm/amd/amdgpu/../ras/rascore/ras_core.c:531 ras_core_ras_interrupt_detected()
	error: we previously assumed 'ras_core' could be null (see line 527)

drivers/gpu/drm/amd/amdgpu/../ras/rascore/ras_core.c
    525 bool ras_core_ras_interrupt_detected(struct ras_core_context *ras_core)
    526 {
    527         if (ras_core && ras_core->sys_fn &&
                    ^^^^^^^^
If ras_core is NULL

    528                 ras_core->sys_fn->detect_ras_interrupt)
    529                 return ras_core->sys_fn->detect_ras_interrupt(ras_core);
    530 
--> 531         RAS_DEV_ERR(ras_core->dev, "Failed to detect ras interrupt!\n");
                            ^^^^^^^^^^^^^
Then we are toasted

    532         return false;
    533 }

regards,
dan carpenter
