Namely, it is not really necessary to store the indices of active trip points in the ACPI thermal driver (so as to use them to invoke the appropriate ACPI methods), because they can be readily computed, but IMO it is better to make changes in more steps in order to use this observation. This is still true: It turns out that the notification-handling code in the ACPI thermal driver can be rearranged to iterate over trip points once, with the help of for_each_thermal_trip() called directly under the zone lock, so patch [1/6] adds a helper function for that. This time, however, more changes are made in order to use this new function in the ACPI thermal driver: * One function is relocated (so that the subsequent changes look cleaner) in patch [2/6]. * Two functions are merged into one (so as to prepare the code for the next change) in patch [3/4] * Patch [4/6] changes the ACPI thermal driver to use the function introduced in patch [1/6] and to reduce the number of trip point walks after a notification from the platform firmware from 2 to 1. Next, patch [5/6] drops thermal_zone_device_exec() that is not used any more and patch [6/6] changes the int340x thermal driver to also use the new helper to iterate over trip points, so it need not make risky assumptions regarding the core functionality. Please see the individual patch changelogs for details. Thanks!
