The "asus->throttle_thermal_policy_mode" variable is a u8 so it can't be negative. And we always verify that the value is valid before setting the policy mode so there is no need to check again here. Signed-off-by:

According to ACPI specification the _INI method must be called when device is enumerated first time. After that there is no need to repeat the procedure. Convert the lis3lv02d_acpi_init() to be a stub (Note, we may not remove it because it is called unconditionally by the accelerometer main driver). Signed-off-by:

Alder PCH uses the same Gigabit Ethernet (GBE) device as Tiger Lake PCH which cannot achieve PC10 without ignoring the PMC GBE LTR. Add this work around for Alder Lake PCH as well.

Alder Lake has 14 status registers that are memory mapped. These registers show the status of the low power mode requirements. The registers are latched on every C10 entry or exit and on every s0ix.y entry/exit. Accessing these registers is useful for debugging any low power related activities. Thus, add debugfs entry to access low power mode status registers.

Add initial support for platform_profile where the support is based on availability of ASUS_THROTTLE_THERMAL_POLICY. Because throttle_thermal_policy is used by platform_profile and is writeable separately to platform_profile any userspace changes to throttle_thermal_policy need to notify platform_profile. In future throttle_thermal_policy sysfs should be removed so that only one method controls the laptop power profile. Signed-off-by:

Substate priority levels are encoded in 4 bits in the LPM_PRI register. This value was used as an index to an array whose element size was less than 16, leading to the possibility of overflow should we read a larger than expected priority. In addition to the overflow, bad values could lead to incorrect state reporting. So rework the priority code to prevent the overflow and perform some validation of the register. Use the priority register values if they give an ordering of unique numbers between 0 and the maximum number of states. Otherwise, use a default ordering instead. Reported-by:
