    My macbook infrared remote control was broken by commit
    bd25f4dd ("HID: hiddev: use
    usb_find_interface, get rid of BKL").
    
    This device appears in dmesg as:
    apple 0003:05AC:8242.0001: hiddev0,hidraw0: USB HID v1.11 Device
    [Apple Computer, Inc. IR Receiver] on usb-0000:00:1d.2-1/input0
    
    It stopped working as lircd was getting ENODEV when opening /dev/usb/hiddev0.
    
    AFAICS hiddev_driver is a dummy driver so usb_find_interface(&hiddev_driver)
    does not find anything.
    
    The device is associated with the usbhid driver, so let's do
    usb_find_interface(&hid_driver) instead.
    
    $ ls -l /sys/devices/pci0000:00/0000:00:1d.2/usb7/7-1/7-1:1.0/usb/hiddev0/device/driver
    lrwxrwxrwx 1 root root 0 2010-09-12 16:28 /sys/devices/pci0000:00/0000:00:1d.2/usb7/7-1/7-1:1.0/usb/hiddev0/device/driver -> ../../../../../../bus/usb/drivers/usbhid
