When user space updates the trip point there is a deadlock, which results in caller gets blocked forever. Commit05eeee2b51("thermal/core: Protect sysfs accesses to thermal operations with thermal zone mutex"), added a mutex for tz->lock in the function trip_point_temp_store(). Hence, trip set callback() can't call any thermal zone API as they are protected with the same mutex lock. The callback here calling thermal_zone_device_enable(), which will result in deadlock. Move the thermal_zone_device_enable() to proc_thermal_pci_probe() to avoid this deadlock.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
