clear_intel_crtc_state() uses the stack for saving a temporary copy of certain bits of the inherited crtc_state before clearing the unwanted bits. This pushes it over the stack limit for my little 32b Pineview, so move the temporary allocation to the heap instead. As we now use a zeroed struct, we can copy the whole extended state back to both preserve what bits need to be preserved and zero the rest.

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.
