2015-12-28T12:41:11+00:00

to_hid_device() macro is defined in both hid-lg4ff.c and
hid-logitech-hidpp.c. So I move it to include/linux/hid.h.

HID: logitech: Add support for G29

2015-11-06T20:18:06+00:00

At present the G29 is mis-identified as a DFGT, this patch ensures
that the wheel is correctly detected and allows setting the LEDs and
turning range via the '/sys' interface.

This wheel can also emulate other types of Logitech wheels.

HID: hid-lg4ff: Protect concurrent access to output HID report

2015-05-07T14:27:16+00:00

Protect concurrent access to output HID report with a spinlock. The HID report
structure used to submit commands to wheels is shared amongst all functions that
need to do so and some of these functions can be executed in parallel.
Additionally, lg4ff_play() can be called from interrupt context by ff-memless
module. Locking is necessary to prevent sending bogus data to the wheels.
