Protect the code in udl_get_edid_block() with drm_dev_enter() and drm_dev_exit(), so that all callers automatically invoke it. The function uses hardware resources, which can be hot-unplugged at any time. The other code in udl_connector_detect() does not use the resources of the hardware device and therefore does not require protection. This change will allow to use udl_get_edid_block() in various contexts easily.

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.
