2025-02-03HID: winwing: Add NULL check in winwing_init_led()Charles Han
devm_kasprintf() can return a NULL pointer on failure,but this returned value in winwing_init_led() is not checked. Add NULL check in winwing_init_led(), to handle kernel NULL pointer dereference error.

These structs are never modified, so mark them as const. Signed-off-by: Thomas Weißschuh <linux@weissschuh.net> Link: https://patch.msgid.link/20240804-hid-const-winwing-v1-1-5a6c714753b1@weissschuh.net Signed-off-by: Benjamin Tissoires <bentiss@kernel.org>
2024-08-27HID: change return type of report_fixup() to constThomas Weißschuh
By allowing the drivers to return a "const *" they can constify their static report arrays. This makes it clear to driver authors that the HID core will not modify those reports and they can be reused for multiple devices. Furthermore security is slightly improved as those reports are protected against accidental or malicious modifications.

2024-04-03HID: Add WinWing Orion2 throttle supportIvan Gorinov
WinWing Orion2 throttle works with Linux out of box, but the kernel sees only 16 of 47 buttons on the throttle base. This module enables all buttons, and also adds LED controls. Button numbers 0 .. 63 on Orion2 are reserved for throttle grip; the throttle base buttons have numbers 64 .. 110. Linux kernel HID subsystem only supports up to 80 buttons. Remap throttle base buttons to numbers 32 .. 78, reserving only numbers 0 .. 31 for buttons on the grip handle. Changes since v2: - Fixed automatic line wraps added by mail client Changes since v1: - Fixed formatting of descriptor byte array; - Using product codes of Winwing grips in config.
