    SubjectRe: [PATCH,v2] acpi: thermal: display forced passive trip points in proc
    Date
    Users can force a passive trip point for a thermal zone that does not
    have _PSV defined in ACPI by setting the passive attribute in sysfs.
    It's useful to display such trip points in /proc/acpi/thermal_zone.

    .../TZ1/cooling_mode:<setting not supported>
    .../TZ1/polling_frequency:polling frequency: 10 seconds
    .../TZ1/state:state: ok
    .../TZ1/temperature:temperature: 53 C
    .../TZ1/trip_points:critical (S5): 110 C
    .../TZ1/trip_points:passive (forced): 95 C

    And if not set (passive is 0):
    .../TZ1/trip_points:passive (forced):<not set>

    I noticed I forgot the linefeed and thought of a further improvement.
