The variable ret is reassigned and the value EINVAL is never used. Thus, remove the unused assignments.

case I915_CONTEXT_PARAM_PERSISTENCE:
if (args->size)ret = -EINVAL; ret = proto_context_set_persistence(fpriv->dev_priv, pc, args->value);AFAICT fix should end up with code like this:
if (args->size) ret = -EINVAL; else ret = proto_context_set_persistence(...) break;
Alternatively move args->size checking into proto_context_set_persistence to align with set_persistence().

Thanks for reviewing! I sent the V2 patch, modified according to your suggestion.
