Subject: [PATCH v2] thermal: provide an UAPI header file
include/linux/thermal.h contains definitions for the Thermal generic
netlink family, but none of the valuable information relevant to
user-space such as the Genl family name, multicast group, version or
command set and data types is exported to user-space.
Export all the relevant generic netlink information to user-space to
make this genl family usable by user-space, and while at it, export
THERMAL_NAME_LENGTH since it limits name length for thermal_hwmon
devices.
Kbuild and MAINTAINERS are also updated accordingly to reflect this new
file: include/uapi/linux/thermal.h.
Signed-off-by: Florian Fainelli <f.fainelli@...il.com>

Changes in v2:
- rebase against Eduardo's thermal/next tree
