From 03f3a9107f5e848a42f25e3ab133db9f3b6546c7 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 13 Sep 2013 11:32:49 -0700 Subject: hv: use dev_groups for device attributes This patch is the first in a series that moves the hv bus code to use the dev_groups field instead of dev_attrs, as dev_attrs is going away in future kernel releases. It moves the id sysfs file to the dev_groups structure, and creates the needed show/store functions, instead of relying on one "universal" function for this. By doing this, it removes the need for this to be in a temporary structure. Tested-by: "K. Y.

So, if extcon device has the parent device, it should set the pointer of parent device to edev.dev.parent in extcon device driver instead of in extcon_dev_register().
