HID: fix hiddev's use of usb_find_interface
My macbook infrared remote control was broken by commit
bd25f4dd6972755579d0ea50d1a5ace2e9b00d1a ("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
