This cleanups 2 things: 1) The first time we loop over the crtc-s, to compare framebuffers, fb1 may get set to NULL by the fb1 = CRTC_FB(crtci); statement and then we call to_vbox_framebuffer() on it. The result of this call is only used for an address comparison, so we don't end up dereferencing the bad pointer, but still it is better to not do this. 2) Since we already figure out the first crtc with a fb in the first loop and store that in fb1, there is no need to loop over the crtc-s again just to find the first crtc with a fb again.

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.
