if (!smu_table->hardcode_pptable)
smu_table->hardcode_pptable = kzalloc(size, GFP_KERNEL);
- if (!smu_table->hardcode_pptable) {
- ret = -ENOMEM;
- goto failed;
- }
+ if (!smu_table->hardcode_pptable)
+ return -ENOMEM;
I guess it's better to put the second check of hardcode_pptable into first if condition section like:
if (!smu_table->hardcode_pptable) {
smu_table->hardcode_pptable = kzalloc(size, GFP_KERNEL);
if (!smu_table->hardcode_pptable)
return -ENOMEM;
}
Regards,
Guchun

Subject: [PATCH V2 1/7] drm/amd/pm: drop unneeded lock protection smu->mutex
As all those APIs are already protected either by adev->pm.mutex or smu->message_lock.
