When a DSS output is (dis)connected the omapdss_output_(un)set_device() function performs a sanity check to ensure that the output isn't already (dis)connected. The check is unnecessary as those situations should never happen, but can nonetheless be useful to catch driver bugs. To prepare for removal of the omapdss_output_(un)set_device() functions move the connection check to the omapdss_device_connect() function. The omapdss_device_disconnect() already contains a corresponding check.

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.
