* HID: Drop NULL test on list_entry resultJulia Lawall2009-07-22
| | | | | | | | | | | | | | | | | | | | | | | | list_entry, which is an alias for container_of, cannot return NULL, as there is no way to add a NULL value to a doubly linked list. A simplified version of the semantic match that findds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r@ expression x,E; statement S1,S2; position p,p1; @@ *x = list_entry@p(...) ... when != x = E *if@p1 (x == NULL) S1 else S2 // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

* HID: autocentering support for Logitech G25 Racing WheelSergey Belyashov2009-05-13
| | | | | | | | | | | | Some months ago I send patch which adds autocentering for Logitech MOMO Wheel. Now I have access to Logitech G25 Racing Wheel and test autocentering for it. I write patch for current kernel to support autocentering for G25 in legacy mode (this device supports other modes, but after switching device reconnects with ID 0xc299 and FF support comes out) and others Logitech (Driving Force, Formula Force Ex etc) wheels with ID 046d:c294.

* HID: Autocentering support for Logitech MOMO Racing WheelSergey Belyashov2008-10-14
| | | | | | | | | | | Current kernel has no support for autocentering for Logitech wheels. By default autocentering enabled in wheel and constant effect does not work properly. Using USB sniffer I found command which change autocentering settings: 0xFE, 0x0D, 0x0R, 0x0L, 0x80, 0x00, 0x00, where R - clockwise force, L - counter-clockwise (0x0-0xF, 0xC = 100%).
