The only thing in xe_gt_remove() that really needs to happen on the device remove callback is the xe_uc_remove(). That's because of the following call chain: xe_gt_remove() xe_uc_remove() xe_gsc_remove() xe_gsc_proxy_remove() Move xe_gsc_proxy_remove() to be handled as a xe_device_remove_action, so it's recorded when it should run during device removal. The rest can be handled normally by devm infra. Besides removing the deep call chain above, xe_device_probe() doesn't have to unwind the gt loop and it's also more in line with the xe_device_probe() style.
