2009-05-11HID: add NOGET quirk for devices from CH ProductsAlan Stern2-0/+8
This patch (as1240) adds the NOGET quirk for three devices from CH Products: the Pro pedals, the Combatstick joystick, and the Flight-Sim yoke. Without these quirks, the devices haven't worked for many kernel releases. Sometimes replugging them after boot-up would get them to work and sometimes they wouldn't work at all.

If the device is not claimed by hid-input (i.e devices driver by userspace hiddev/hidraw-based drivers, or completely detached from HID and driver by libusb), we must not check the hid->inptus, as it is not guaranteed to be initialized, as this is performed only for devices handled by hid-input.

2009-03-30HID: fix race between usb_register_dev() and hiddev_open()Oliver Neukum1-0/+5
upon further thought this code is still racy. retval = usb_register_dev(usbhid->intf, &hiddev_class); here you open a window during which open can happen if (retval) { err_hid("Not able to get a minor for this device."); hid->hiddev = NULL; kfree(hiddev); return -1; } else { hid->minor = usbhid->intf->minor; hiddev_table[usbhid->intf->minor - HIDDEV_MINOR_BASE] = hiddev; and will fail because hiddev_table hasn't been updated The obvious fix of using a mutex to guard hiddev_table doesn't work because usb_open() and usb_register_dev() take minor_rwsem and we'd have an AB-BA deadlock. We need a lock usb_open() also takes in the right order and that leaves only one option, BKL. I don't like it but I see no alternative.

2009-03-25HID: autosuspend support for USB HIDOliver Neukum5-103/+396
This uses the USB busy mechanism for aggessive autosuspend of USB HID devices. It autosuspends all opened devices supporting remote wakeup after a timeout unless - output is being done to the device - a key is being held down (remote wakeup isn't triggered upon key release) - LED(s) are lit - hiddev is opened As in the current driver closed devices will be autosuspended even if they don't support remote wakeup. The patch is quite large because output to devices is done in hard interrupt context meaning a lot a queuing and locking had to be touched. The LED stuff has been solved by means of a simple counter. Additions to the generic HID code could be avoided. In addition it now covers hidraw. It contains an embryonic version of an API to let the generic HID code tell the lower levels which capabilities with respect to power management are needed.

2009-03-16Rationalize fasync return valuesJonathan Corbet1-4/+1
Most fasync implementations do something like: return fasync_helper(...); But fasync_helper() will return a positive value at times - a feature used in at least one place. Thus, a number of other drivers do: err = fasync_helper(...); if (err < 0) return err; return 0; In the interests of consistency and more concise code, it makes sense to map positive return values onto zero where ->fasync() is called.

2009-03-11HID: fix waitqueue usage in hiddevJohannes Weiner1-1/+1
DECLARE_WAITQUEUE doesn't initialize the wait descriptor's task_list to 'empty' but to zero. prepare_to_wait() will not enqueue the descriptor to the waitqueue and finish_wait() will do list_del_init() on a list head that contains NULL pointers, which oopses. This was introduced by 079034073 "HID: hiddev cleanup -- handle all error conditions properly". The prior code used an unconditional add_to_waitqueue() which didn't care about the wait descriptor's list head and enqueued the thing unconditionally. The new code uses prepare_to_wait() which DOES check the prior list state, so use DEFINE_WAIT instead.

2009-01-07USB: change interface to usb_lock_device_for_reset()Alan Stern1-5/+4
This patch (as1161) changes the interface to usb_lock_device_for_reset(). The existing interface is apparently not very clear, judging from the fact that several of its callers don't use it correctly. The new interface always returns 0 for success and it always requires the caller to unlock the device afterward. The new routine will not return immediately if it is called while the driver's probe method is running. Instead it will wait until the probe is over and the device has been unlocked. This shouldn't cause any problems; I don't know of any cases where drivers call usb_lock_device_for_reset() during probe.
