[ Upstream commit 7569406e95f2353070d88ebc88e8c13698542317 ]
The function thermal_genl_auto() does not free the allocated message
in the error path. Fix that by putting a out label and jump to it
which will free the message instead of directly returning an error.

[ Upstream commit 24b216b2d13568c703a76137ef54a2a9531a71d8 ]
The thermal netlink has been extended with more commands which require
an encoding with more information. The generic encoding function puts
the thermal zone id with the command name. It is the unique
parameters.
The next changes will provide more parameters to the command. Set the
scene for those new parameters by making the encoding function more
generic.

The thermal framework implements a netlink notification mechanism to
be used by the userspace to have a thermal configuration discovery,
trip point changes or violation, cooling device changes notifications,
etc...
This library provides a level of abstraction for the thermal netlink
notification allowing the userspace to connect to the notification
mechanism more easily. The library is callback oriented.
