i915_guc_info() (part of debugfs output) tries to avoid holding struct_mutex for a long period by copying onto the stack. This causes a warning that the stack frame is massive, so stop doing that. We can even forgo holding the struct_mutex here as that doesn't serialise the values being read (and the lists used exist for the device lifetime). v2: Skip printing anything if guc->execbuf_client is disabled (avoids potential NULL dereference).
