platform/x86: asus-wmi: Fix thermal profile initialization

2024-10-26T11:03:10Z

When support for vivobook fan profiles was added, the initial call to throttle_thermal_policy_set_default() was removed, which however is necessary for full initialization. Fix this by calling throttle_thermal_policy_set_default() again when setting up the platform profile.

platform/x86:intel/pmc: Revert "Enable the ACPI PM Timer to be turned off when suspended"

2024-10-21T14:04:00Z

Commit e86c8186d03a ("platform/x86:intel/pmc: Enable the ACPI PM Timer to be turned off when suspended") can cause the suspend process to hang as the pmcdev->lock in the pmc_core_acpi_pm_timer_suspend_resume might already be held by the pmc_core_mphy_pg_show or pmc_core_pll_show if the userspace gets frozen when these functions are being executed. Also, pmc_core_acpi_pm_timer_suspend_resume must not sleep, as this function is called indirectly by the tick_freeze function in kernel/time/tick-common.c, which holds the spinlock. Revert the changes for now to fix these issues.

2024-10-06T10:50:50Z

x86_android_tablet_remove() frees the pdevs[] array, so it should not be used after calling x86_android_tablet_remove(). When platform_device_register() fails, store the pdevs[x] PTR_ERR() value into the local ret variable before calling x86_android_tablet_remove() to avoid using pdevs[] after it has been freed.
