The PSCI checker suspend_test_thread() function (ie executed for the
suspend test) requires an on-stack timer to carry out the test it
executes; it sets it up through the setup_timer_on_stack() API.
setup_timer_on_stack() requires its counterpart destroy_timer_on_stack()
to be called when the timer is disposed of but the PSCI checker code is
currently missing that call, leaving the timer object in an incosistent
state when the PSCI checker stops the thread executing the suspend
test.
Add the missing destroy_timer_on_stack() call to fix the omission.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
