From: Anirudh Rayabharam <mail@xxxxxxxxxxxxx> [ Upstream commit bbeb18f27a44ce6adb00d2316968bc59dc640b9b ] In smcd_alloc_dev(), if alloc_ordered_workqueue() fails, properly catch it, clean up and return NULL to let the caller know there was a failure. Move the call to alloc_ordered_workqueue higher in the function in order to abort earlier without needing to unwind the call to device_initialize().
