For normal connector detect, there's really no point in trying dual mode detect if the connector is disconnected. We can simplify the detect sequence by skipping it. Since intel_hdmi_dp_dual_mode_detect() is only called when EDID is present, we can drop the has_edid parameter. The functional effect is speeding up disconnected connector detection ever so slightly, and, combined with firmware EDID, also stop logging about assuming dual mode adaptor. It's a bit subtle, but this will also skip dual mode detect if the connector is force connected and a) there's no EDID of any kind, normal or override/firmware or b) there's EDID but it does not indicate digital. These are corner cases no matter what, and arguably forcing should not be limited by dual mode detect.

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.
