platform/x86: think-lmi: Fix current password length check

2026-08-18T16:28:32+00:00

current_password_store() checks the password length before removing the trailing newline, which can reject valid passwords that are exactly ->maxlen bytes long. It also passes ->maxlen to strscpy(), which truncates passwords without a newline. Use strchrnul() to measure the password length up to the newline, then copy that many bytes and add a trailing NUL terminator using strscpy().

platform/x86: redmi-wmi: report EC state change events

2026-08-18T14:30:49+00:00

The Redmibook EC/firmware fully handles the keyboard backlight cycle, the OEM preset power mode (Fn+K) and the Fn lock toggle by itself, and sends a WMI event carrying the resulting state in the third payload byte. These events are currently swallowed with KE_IGNORE, so userspace never learns that the state changed and cannot give the user any feedback (OSD), even though the WMI event is the only notification channel for these EC-driven changes. Report them as key presses instead: - keyboard backlight cycle -> KEY_KBDILLUMTOGGLE - OEM preset power mode -> KEY_PERFORMANCE - Fn lock toggle -> KEY_FN_ESC Desktops that only look at the keycode get the usual hotkey behaviour; since sparse-keymap emits MSC_SCAN with the raw payload before the key event, an OSD daemon can additionally recover the exact new state from byte 2 (e.g. backlight Off/Low/High/Auto is 0x00/0x05/0x0a/0x80). Note that the power mode event must keep being read from the WMI device in any case: on the TM2209 the ACPI event handler (EV20) applies the mode change as a side effect of building the event payload for _WED. Tested on Redmi Book Pro 15 2023 (TM2209).

OneXPlayer X2 Mini Pro is a new Strix Halo handheld. It ships the same system board as the OneXPlayer APEX and uses the same registers as the OneXPlayer Fly devices.

platform/x86: thinkpad_acpi: Fix fan speed reporting on Edge E330

2026-08-18T14:30:44+00:00

The ThinkPad Edge E330 with H3 firmware uses the non-standard EC fan register block. Without a matching quirk, thinkpad_acpi reads the legacy tachometer registers and reports 0 RPM. Add the H3 BIOS family to TPACPI_FAN_NS so the driver reads the fan period from EC register 0x95 using the existing non-standard reporting path. Tested on a ThinkPad Edge E330 with BIOS H3ET77WW and EC H3EC35WW.

platform/x86: think-lmi: Fix certificate thumbprint sysfs output

2026-08-18T14:30:34+00:00

cert_thumbprint() already returns the accumulated output length, but certificate_thumbprint_show() adds that value to count again, making the next line use the wrong offset. Errors returned by cert_thumbprint() are also ignored and their negative values added to count. Assign the total length to count instead and propagate errors correctly.
