HID: core: move Usage Page concatenation to Main item

2019-05-31T13:48:29Z

[ Upstream commit 58e75155009cc800005629955d3482f36a1e0eec ] As seen on some USB wireless keyboards manufactured by Primax, the HID parser was using some assumptions that are not always true. In this case it's s the fact that, inside the scope of a main item, an Usage Page will always precede an Usage. The spec is not pretty clear as 6.2.2.7 states "Any usage that follows is interpreted as a Usage ID and concatenated with the Usage Page". While 6.2.2.8 states "When the parser encounters a main item it concatenates the last declared Usage Page with a Usage to form a complete usage value." Being somewhat contradictory it was decided to match Window's implementation, which follows 6.2.2.8. In summary, the patch moves the Usage Page concatenation from the local item parsing function to the main item parsing function.

HID: core: Fix size as type u32

2018-04-24T07:34:12Z

commit 6de0b13cc0b4ba10e98a9263d7a83b940720b77a upstream. When size is negative, calling memset will make segment fault. Declare the size as type u32 to keep memset safe. size in struct hid_report is unsigned, fix return type of hid_report_len to u32.

HID: Add vendor specific usage pages for Logitech G920

2015-11-20T09:30:00Z

The Logitech G920 uses a couple of vendor specific usage pages, which results in incorrect number of axis/buttons being detected. This patch adds these pages to the 'ignore' list. Reported-by: Elias Vanderstuyft Signed-off-by: Simon Wood Reviewed-by: Benjamin Tissoires Signed-off-by: Jiri Kosina

HID: hid-input: allow input_configured callback return errors

2015-11-05T17:51:50Z

When configuring input device via input_configured callback we may encounter errors (for example input_mt_init_slots() may fail). Instead of continuing with half-initialized input device let's allow driver indicate failures.

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 ...
