      HID: wacom: Ignore contacts in excess of declared contact count · 1b5d514a
      由 Jason Gerecke 提交于 
      The reports sent from some touch devices (e.g. the Cintiq 24HDT) contain
junk data in the contact slots which follow the final "valid" contact.
To avoid forwarding it to usrspace, we store the reported contact count
during the pre-process phase and then only process that many contacts.
If a device sends its contacts across multiple reports (what Microsoft
refers to as "hybrid" mode) then the contact count will be zero for
reports other than the first.

      HID: wacom: Perform all event processing as part of report processing · 06324e0c
      由 Jason Gerecke 提交于 
      In some cases, we need access to information before it becomes available
to the 'event' handler. In particular, for some devices we cannot properly
process the finger data without first knowing the "contact count" at the
very end of the report (e.g. the Cintiq 24HDT touch screen, when forced
through the GENERIC codepath).

Since the HID subsystem doesn't provide a way to take action before 'event'
is called, we take a cue from hid-multitouch.c and add a pre-process step
within the 'report' handler that performs the same function.

      HID: wacom: Set default device name to value from wacom->features · 2bdd163c
      由 Jason Gerecke 提交于 
      Allocated input devices should not use the 'pen_name' by default since
we do not know at that point in time if that is an appropriate choice
of name. Instead, use the (tool-agnostic) name that is stored in the
device's 'wacom_features' structure. This also has the nice side-effect
of requring us to be explicit about the naming of the pen device, as
we already are for touch and pad devices.

      HID: wacom: Properly free inputs if 'wacom_allocate_inputs' fails · d9f2d203
      由 Jason Gerecke 提交于 
      The 'wacom_allocate_inputs' function tries to allocate three input devices: one
each for the pen, touch, and pad. The pointers that are returned by the
'wacom_allocate_input' calls are temporarily stored to local variables where
they are checked to ensure they're non-null before storing them in the
'wacom_wac' structure. If an allocation fails,  the 'wacom_free_inputs'
function is called to reclaim the memory. Unfortunately, 'wacom_free_inputs' is
called prior to the pointers being copied, so it is not actually able to free
anything.

This patch has the calls to 'wacom_allocate_input' store the pointer directly
in the 'wacom_wac' structure where they can be freed. Also, it replaces the
call to 'wacom_free_inputs' with the (more general) 'wacom_clean_inputs' and
removes the no-longer-used function.

 unnecessary checks")]

      HID: usbhid: add Chicony/Pixart usb optical mouse that needs QUIRK_ALWAYS_POLL · 7250dc3f
      由 Herton R. Krzesinski 提交于 
      I received a report from an user of following mouse which needs this quirk:

usb 1-1.6: USB disconnect, device number 58
usb 1-1.6: new low speed USB device number 59 using ehci_hcd
usb 1-1.6: New USB device found, idVendor=04f2, idProduct=1053
usb 1-1.6: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-1.6: Product: USB Optical Mouse
usb 1-1.6: Manufacturer: PixArt
usb 1-1.6: configuration #1 chosen from 1 choice
input: PixArt USB Optical Mouse as /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.6/1-1.6:1.0/input/input5887
generic-usb 0003:04F2:1053.16FE: input,hidraw2: USB HID v1.11 Mouse [PixArt USB Optical Mouse] on usb-0000:00:1a.0-1.6/input0

The quirk was tested by the reporter and it fixed the frequent disconnections etc.
