567af70520 thermal: Replace pr_warn() with pr_warn_once() in user_space_bind() 
Use pr_warn_once() instead of pr_warn() to print the user space
governor deprecation message in user_space_bind() to reduce the
kernel log noise.

0275c9fb0e thermal/core: Make the userspace governor deprecated 
The userspace governor is sending temperature when polling is active
and trip point crossed events. Nothing else.

AFAICT, this governor is used with custom kernels making the userspace
governor co-existing with another governor on the same thermal zone
because there was no notification mechanism, implying a hack in the
framework to support this configuration.

The new netlink thermal notification is able to provide more
information than the userspace governor and give the opportunity to
the users of this governor to replace it by a dedicated notification
framework.

The userspace governor will be removed as its usage is no longer
needed.

Add a warning message to tell the userspace governor is deprecated.

0015d9a2a7 thermal/governors: Prefix all source files with gov_ 
Bang-bang governor source file is prefixed with gov_. Do the same for
other governors for consistency so they're easy to find in the sources.
