Hardware may not respond to a request for the HID_DG_CONTACTMAX feature and we should be tolerant of such a failure. This is especially true when using hid-replay where the hardware doesn't exist, but also for devices attached to a flaky bus. This patch increases the number of allowable retries to match other calls to 'wacom_get_report' and also provides a fallback which forces 'touch_max = 16' (enough for any Wacom device seen so far).

Retrying on -EPIPE makes very little sense since this typically indicates a problem that will not just disappear on its own. For instance, the USB documentation states that it will be sent if the endpoint is stalled or the device has disconnected. Instead, we should retry if -EAGAIN is received since this indicates a temporary error condition such as a busy bus. In addition to adjusting the conditions we retry under, we also log an error on failure so that we can be aware of what's going on.

The last patch was careful to maintain backwards-compatible behavior by forcing device_type to BTN_TOOL_PEN (and printing a warning) if it were still uninitialized after scanning the HID descriptor and applying quirks. We should be more strict with HID_GENERIC devices, however, since there is no a priori guarantee that it is a tablet or touchpad. If the device_type is still uninitialized for a HID_GENERIC device then we assume that it isn't something the driver can work with and so fail the probe.

Currently, we assume a device_type of BTN_TOOL_PEN before scanning the HID descriptor and then change the device_type if what we discover proves that assumption wrong. This way of doing things makes it more difficult to figure out if a device (particularly a HID_GENERIC device) actually does tablet/touch input or is something completley different. This patch leaves device_type at its initial value of 0 and then calls 'wacom_parse_hid' for every device (not just those that have touch). As we map the usages, we can set the device_type as before. After we're finished, we can then check if the value is still zero and do whatever is most appropriate. Detecting the pen can be a little tricky on most Wacom devices because the descriptors describe opaque blobs. Fortunately, older Wacom tablets have the HID_DG_DIGITIZER usage on the pen's application collection and newer tablets seem to have a similar vendor-defined usage that we can trigger on.

The naming logic currently assumes that all devices will be a pen, finger, or pad. Though this has historically been the case, the new HID_GENERIC catch-all may cause us to probe devices with Wacom's 056A VID which aren't any of these types (e.g. the "Cintiq 24HDT Monitor Control"). This patch updates the logic so that no suffix will be added to the device name if the device type is unknown.

HID generic devices share the same default name, "Wacom HID". This causes userland programs to show same device names for different devices, which would confuse end users with same device names for different devices too. This patch uses name retrieved from HID descriptor, if a meaningful name is reported. Otherwise, affix its product ID to "Wacom HID". Names from descriptor may contain extra whitespaces. To comfort readers' eyes, we removed those extra whitespaces too.

Pull HID updates from Jiri Kosina: - quite a few firmware fixes for RMI driver by Andrew Duggan - huion and uclogic drivers have been substantially overlaping in functionality laterly. This redundancy is fixed by hid-huion driver being merged into hid-uclogic; work done by Benjamin Tissoires and Nikolai Kondrashov - i2c-hid now supports ACPI GPIO interrupts; patch from Mika Westerberg - Some of the quirks, that got separated into individual drivers, have historically had EXPERT dependency. As HID subsystem matured (as well as the individual drivers), this made less and less sense. This dependency is now being removed by patch from Jean Delvare - Logitech lg4ff driver received a couple of improvements for mode switching, by Michal Malý - multitouch driver now supports clickpads, patches by Benjamin Tissoires and Seth Forshee - hid-sensor framework received a substantial update; namely support for Custom and Generic pages is being added; work done by Srinivas Pandruvada - wacom driver received substantial update; it now supports i2c-conntected devices (Mika Westerberg), Bamboo PADs are now properly supported (Benjamin Tissoires), much improved battery reporting (Jason Gerecke) and pen proximity cleanups (Ping Cheng) - small assorted fixes and device ID additions * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid: (68 commits) HID: sensor: Update document for custom sensor HID: sensor: Custom and Generic sensor support HID: debug: fix error handling in hid_debug_events_read() Input - mt: Fix input_mt_get_slot_by_key HID: logitech-hidpp: fix error return code HID: wacom: Add support for Cintiq 13HD Touch HID: logitech-hidpp: add a module parameter to keep firmware gestures HID: usbhid: yet another mouse with ALWAYS_POLL HID: usbhid: more mice with ALWAYS_POLL HID: wacom: set stylus_in_proximity before checking touch_down HID: wacom: use wacom_wac_finger_count_touches to set touch_down HID: wacom: remove hardcoded WACOM_QUIRK_MULTI_INPUT HID: pidff: effect can't be NULL HID: add quirk for PIXART OEM mouse used by HP HID: add HP OEM mouse to quirk ALWAYS_POLL HID: wacom: ask for a in-prox report when it was missed HID: hid-sensor-hub: Fix sparse warning HID: hid-sensor-hub: fix attribute read for logical usage id HID: plantronics: fix Kconfig default HID: pidff: support more than one concurrent effect ...
