After resume/online turbo limit ratio (TRL) is restored partially if the admin explicitly changed TRL from user space. A hash table is used to store SST mail box and MSR settings when modified to restore those settings after resume or online. This uses a struct isst_cmd field "data" to store these settings. This is a 64 bit field. But isst_store_new_cmd() is only assigning as u32. This results in truncation of 32 bits. Change the argument to u64 from u32.

platform/x86: thinkpad_acpi: disable ACPI fan access for T495* and E560 2025-04-10T12:44:44+00:00 Eduard Christian Dumitrescu eduard.c.dumitrescu@gmail.com 2025-03-24T15:24:42+00:00 537da29aef6d3d0c7834e9f72898785638cce80b commit 2b9f84e7dc863afd63357b867cea246aeedda036 upstream. T495, T495s, and E560 laptops have the FANG+FANW ACPI methods (therefore fang_handle and fanw_handle are not NULL) but they do not actually work, which results in a "No such device or address" error. The DSDT table code for the FANG+FANW methods doesn't seem to do anything special regarding the fan being secondary. The bug was introduced in commit 57d0557dfa49 ("platform/x86: thinkpad_acpi: Add Thinkpad Edge E531 fan support"), which added a new fan control method via the FANG+FANW ACPI methods. Add a quirk for T495, T495s, and E560 to avoid the FANG+FANW methods. Fan access and control is restored after forcing the legacy non-ACPI fan control method by setting both fang_handle and fanw_handle to NULL.
