Subject: Re: [PATCH,v2] acpi: thermal: display forced passive trip points in proc

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.
