From afe5c118bd07edcb00503bd0f4ab83a6e56ae9d8 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 18 Nov 2015 10:07:05 -0700 Subject: [PATCH] staging: comedi: adv_pci_dio: post increment 'subdev' in (*auto_attach) For aesthetics, post-increment the 'subdev' index when used to get a comedi_subdevice pointer instead of incrementing it after the subdevice is initialized.
