Kernel sources for Moto G9 (Play) (Guamp)

The armpmu uses get_event_idx callback to allocate an event counter for a given event, which marks the selected counter as "used". Now, when we delete the counter, the arm_pmu goes ahead and clears the "used" bit and then invokes the "clear_event_idx" call back, which kind of splits the job between the core code and the backend. To keep things tidy, mandate the implementation of clear_event_idx() and add it for exisiting backends. This will be useful for adding the chained event support, where we leave the event idx maintenance to the backend. Also, when an event is removed from the PMU, reset the hw.idx to indicate that a counter is not allocated for this event, to help the backends do better checks. This will be also used for the chain counter support.

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.
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.
