*	HID: fix a lockup regression when using force feedback on a PID device	Anssi Hannula	2008-10-14	1	-2/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Commit 8006479c9b75fb6594a7b746af3d7f1fbb68f18f introduced a spinlock in input_dev->event_lock, which is locked when handling input events. However, the hid-pidff driver sleeps when handling events as it waits for reports being sent to the device before changing the report contents again. This causes a system lockup when trying to use force feedback with a PID device, a regression introduced in 2.6.24 and 2.6.23.15. Fix it by extracting the raw report data from struct hid_report immediately when hid_submit_report() is called, therefore allowing drivers to change the contents of struct hid_report immediately without affecting the already-queued transfer. In hid-pidff, re-add the removed usbhid_wait_io() to pidff_erase_effect() instead, to prevent a full report queue from causing the submission to fail, thus not freeing up device memory. pidff_erase_effect() is not called while dev->event_lock is held.

*	HID: fix autocentering of PID devices	Diogo Kastrup	2007-07-09	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \| \|	When setting the autocentering of PID devices, PID_DIRECTION_ENABLE is not being explicitely set to 1. This results in autocentering working only on the vertical axis when this field is preset to 0. Fix that by setting it explicitely to 1 when preparing the set_effect report for autocentering spring effect.

*	USB HID: move usbhid code from drivers/usb/input to drivers/hid/usbhid	Jiri Kosina	2007-04-11	1	-0/+1331
	Separate usbhid code into dedicated drivers/hid/usbhid directory as discussed previously with Greg, so that it eases maintaineance process. Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
