As a result of converting to the stream-aware state functions, commitbc0e8d91fe("media: v4l: subdev: Switch to stream-aware state functions") caused the sd pointer of the state passed to the v4l2_subdev_state_get_crop() function to be dereferenced. It however missed that the atmel-isi driver creates the v4l2_subdev_state instance on the stack (which it shouldn't do, but that's a separate problem), without initializing the sd field. This results in a null pointer dereference. Fix it by initializing the sd field.

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.
