From: Anssi Hannula Date: Fri, 19 Jan 2007 17:28:17 +0000 (+0200) Subject: HID: put usb_interface instead of usb_device into hid->dev to fix udevinfo breakage X-Git-Tag: v2.6.20-rc6~55^2~1 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=be8209753b014f2d7a92b2ec3ff82db478fc86d1;p=linux-2.6-omap-h63xx.git HID: put usb_interface instead of usb_device into hid->dev to fix udevinfo breakage The commit 4916b3a57fc94664677d439b911b8aaf86c7ec23 introduced a hid regression between 2.6.19 and 2.6.20-rc1. The device put in input_dev->cdev is now of type usb_device instead of usb_interface. Before: > # readlink -f /sys/class/input/input6/event4/device > /sys/devices/pci0000:00/0000:00:10.0/usb2/2-1/2-1:1.1 After: > # readlink -f /sys/class/input/input3/event3/device > /sys/devices/pci0000:00/0000:00:10.0/usb1/1-1 This causes breakage: > # udevinfo -q all -n /dev/input/event3 > P: /class/input/input3/event3 > N: input/event3 > S: input/by-path/pci-1-1--event- > E: ID_SERIAL=noserial > E: ID_PATH=pci-1-1- No ID_MODEL, ID_VENDOR, ID_REVISION, ID_TYPE etc etc. Fix this by assigning the intf->dev into hid->dev, and fixing all the users.
