First, we were calling mc_stop() at the top of the function which turns off all MC (memory controller) clients, then checking if the GPU is idle. If it was idle we returned without re-enabling the MC clients which would lead to a blank screen, etc. This patch checks if the GPU is idle before calling mc_stop(). Second, if the reset failed, we were returning without re-enabling the MC clients. This patch re-enables the MC clients before returning regardless of whether the reset was successful or not.
