[PATCH] HID: logitech-dj: add HIDRAW dependency in Kconfig

[Olivier Gay <ogay@logitech.com>]

hid-logitech-dj.c driver needs hidraw to work correctly. Without
hidraw, hid-logitech-dj.c fails during probe() and Logitech
Unifying devices HID reports aren't recognized.

Hi everyone,

this adds a HIDRAW dependency in Kconfig for hid-logitech-dj.c
driver. The driver uses hidraw and needs it to work correctly.

Without hidraw if a Logitech Unifying device is plugged, the driver
fails during probe() and Logitech Unifying devices HID reports aren't
recognized. This has been the cause of some confusion. Some Linux and
Android distributions had HID_LOGITECH_DJ enabled without HIDRAW and
the Unifying mice and keyboards would simply not work (no cursor
tracking / no keyboard typing).

Best regards,

Olivier
