DMC_EVT_CTL_ENABLE cannot be cleared once set. So currently any event we never enable will have DMC_EVT_CTL_ENABLE cleared, whereas any event which has been enabled even once will have DMC_EVT_CTL_ENABLE set. For that reason assert_dmc_loaded() has a special case to ignore any mismatches in DMC_EVT_CTL_ENABLE. Eliminate the special case by always configuring DMC_EVT_CTL_ENABLE based on the original firmware event definition. Now all event handlers will have DMC_EVT_CTL_ENABLE set, whether or not the event has been enabled in the past. All disabled event handlers will still have the event type set to DMC_EVENT_FALSE so they will not actually trigger despite DMC_EVT_CTL_ENABLE being set.

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 reStructuredText 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.
