Dave Jiang 04922b7445 dmaengine: idxd: fix cdev setup and free device lifetime issues ... The char device setup and cleanup has device lifetime issues regarding when parts are initialized and cleaned up. The initialization of struct device is done incorrectly. device_initialize() needs to be called on the 'struct device' and then additional changes can be added. The ->release() function needs to be setup via device_type before dev_set_name() to allow proper cleanup. The change re-parents the cdev under the wq->conf_dev to get natural reference inheritance. No known dependency on the old device path exists.
