Code for registering triggers assumes it's possible to register more than one trigger at a time. In fact, it's unimplemented and there doesn't seem to be a reason to do that. Remove the n_registered param from event_trigger_register() and fix up callers. Doing so simplifies the logic in event_trigger_register to the point that it just becomes a wrapper calling event_command.reg(). It also removes the problematic call to event_command.unreg() in case of failure. A new function, event_trigger_unregister() is also added for callers to call themselves. The changes to trace_events_hist.c simply allow compilation; a separate patch follows which updates the hist triggers to work correctly with the new changes.

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.
