From d3e8ab48db7fdb7b4898d3685f49720a46925902 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 13 Nov 2015 11:11:20 -0700 Subject: [PATCH] staging: comedi: adv_pci1710: 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.
