commita57cc2dbb3upstream. Commit52f04f10b9("thermal: intel: int340x: processor_thermal: Fix deadlock") addressed deadlock issue during user space trip update. But it missed a case when thermal zone device is disabled when user writes 0. Call to thermal_zone_device_disable() also causes deadlock as it also tries to lock tz->lock, which is already claimed by trip_point_temp_store() in the thermal core code. Remove call to thermal_zone_device_disable() in the function sys_set_trip_temp(), which is called from trip_point_temp_store().

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.
