The omapdss_find_output_from_display() function is only used to retrieve the dispc channel corresponding to the display. Return the dispc channel directly, and rename the function to omapdss_device_get_dispc_channel() to match its new purpose. The dssdev->id check is removed as the dssdev is guaranteed to be an output and have a non-zero id, as proved by the lack of crash despite the caller never checking the returned pointer before dereferencing it. As the function is not specific to outputs anymore, move it from output.c to base.c.

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.
