[PATCH v3 0/2] Add new force feedback driver for Mayflash game controller adapters.

[Marcel Hasler]

This patchset adds a new force feedback driver for game controller adapters by Mayflash,
called hid-mf.

These devices identify themselves using the vendor ID of DragonRise but don't actually seem
to be in any way related to those gamepads. They are therefore not in any way compatible with
the hid-dr driver that implements force feedback for regular DragonRise gamepads. In fact, the
protocol used by these adapters is a lot simpler than the one implemented in hid-dr. On the
other hand, because of the multi-input nature of these adapters the new driver needs to setup
memory-less force feedback for four individual input devices.

At the moment only the PS3 adapter is supported. I assume that the other adapters (for Wii U
and GameCube) use the same protocol, but since I don't own any of these (nor any of the gamepads)
I haven't been able to test them.

CHANGES from v1:
* Added IS_ENABLED(CONFIG_HID_MAYFLASH) to hid_have_special_driver[] in hid-core.c
* Proper iteration over hid->inputs in mf_init() in hid-mf.c
* Use consistent naming of 'struct hid_device *hid' in hid-mf.c

CHANGES from v2:
* NONE, only resubmission
