Here is a sequence of fixes and documentation improvements
thermal code base. This should be first of a series of changes
I am planing to send out.

On this very first there is no change in functionality, as
the patches only change symbol names and updates kernel-doc
comments and their formants.



Eduardo Valentin (11):
  thermal: use strlcpy instead of strcpy
  thermal: update driver license
  thermal: rename notify_thermal_framework to thermal_notify_framework
  thermal: rename get_thermal_instance to thermal_instance_get
  thermal: rename get_tz_trend to thermal_zone_trend_get
  thermal: use EXPORT_SYMBOL_GPL
  thermal: update kernel-doc for thermal_zone_bind_cooling_device
  thermal: update kernel-doc for thermal_zone_unbind_cooling_device
  thermal: update kernel-doc for thermal_cooling_device_register
  thermal: update kernel-doc for create_trip_attrs
  thermal: update kernel-doc for thermal_zone_device_register

[PATCH RESEND 02/11] thermal: update driver license

[Eduardo Valentin]

As per the comment at the top of this file, this is a GPLv2 driver.
This patch updates the driver license accordingly.

NACK.

with the change of building all thermal governors into thermal_sys
module, get_thermal_instance becomes an internally helper function,
rather than external API.
thus I think it is okay to use the current name get_thermal_instance.
But you remind me a need a cleanup patch to remove these APIs. :)

How about keeping this patch and resending with a better description? 
Something like:
To follow the prefix names used by the thermal functions,
this patch renames get_thermal_instance to thermal_instance_get.

NACK.

get_tz_trend will not be exported as API any more.

Same comment as in patch 04. How about keeping this patch, but updating 
the commit description? I dont see why not keep one single nameing 
pattern in the file. it makes reading the code more pleasant.

it is not enough.
parameters including const struct thermal_zone_params *tzp,
int passive_delay, and int polling_delay are missing in the

Sorry, I was not clear enough.
I mean we need to update Documentation/thermal/sysfs-api.txt as well,
for thermal_zone_device_register.
Patch will be sent out soon.

I am going to rebase this series on top of your latest -next branch and 
resend with your comments.

I believe name standardization could be still be applied though.
