Currently, the driver just assumes that PM runtime logic succeded resuming the device. That may not be the case, as pm_runtime_get_sync() can fail (but keeping the usage count incremented). Replace the code to use pm_runtime_resume_and_get(), and letting it return the error code. This way, if mtk_vcodec_dec_pw_on() fails, the logic under fops_vcodec_open() will do the right thing and return an error, instead of just assuming that the device is ready to be used.
