Subject: [PATCH 0/2] dell-wmi: Add support for Fn key combinations

This patch series add support for Fn key combinations to dell-wmi driver.
I tested this patch series on laptop Dell Latitude E6440.

Here is Bios DMI table which contains scancode to keycode mapping:

Handle 0xB200, DMI type 178, 80 bytes
OEM-specific Type
        Header and Data:
                B2 50 00 B2 07 01 0C 00 08 01 0A 00 09 01 0B 00
                0A 01 12 00 3B 00 20 00 42 00 18 00 48 00 14 00
                50 00 13 00 10 00 FF 00 11 00 FF 00 12 00 FF 00
                13 00 FF 00 14 00 FF 00 1E 00 FF 00 1F 00 FF 00
                20 00 FF 00 21 00 FF 00 22 00 FF 00 4D 00 16 00
        Strings:

As you can see, more different keys are mapped to one keycode 0xFF.
