The Maxxter KB-BT-001 Bluetooth keyboard, which looks somewhat like the Apple Wireless Keyboard, is using the vendor and product IDs (05AC:0239) of the Apple Wireless Keyboard (2009 ANSI version) <sigh>. But its F1 - F10 keys are marked as sending F1 - F10, not the special functions hid-apple.c maps them too; and since its descriptors do not contain the HID_UP_CUSTOM | 0x0003 usage apple-hid looks for for the Fn-key, apple_setup_input() never gets called, so F1 - F6 are mapped to key-codes which have not been set in the keybit array causing them to not send any events at all. The lack of a usage code matching the Fn key in the clone is actually useful as this allows solving this problem in a generic way. This commits adds a fn_found flag and it adds a input_configured callback which checks if this flag is set once all usages have been mapped. If it is not set, then assume this is a clone and clear the quirks bitmap so that the hid-apple code does not add any special handling to this keyboard. This fixes F1 - F6 not sending anything at all and F7 - F12 sending the wrong codes on the Maxxter KB-BT-001 Bluetooth keyboard and on similar clones.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
