From 6935e0f5181644201894f0b7fbe3d8910c18af05 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Fri, 9 Mar 2012 15:53:42 +0100 Subject: [PATCH] Bluetooth: Remove redundant hdev->parent field We initialize the "struct device" in hci_alloc_dev() for a long time now so we can access hdev->dev.parent directly. Hence, we can drop the temporary field hdev->parent which is used in no other place than hci_add_sysfs(). SET_HCIDEV_DEV() is never called after registering a device by the drivers so we do not overwrite internal device-state. Furthermore, hdev->dev is initialized to 0 by kzalloc() inside hci_alloc_dev() so the default behavior with dev.parent = NULL is kept.
