The compiler doesn't always spot the guard that object is allocated on
the first pass, leading to:
drivers/gpu/drm/i915/selftests/i915_gem_context.c: warning: 'obj' may be used uninitialized in this function [-Wuninitialized]: => 370:8
v2: Make it more obvious by setting obj to NULL on the first pass and
any later pass where we need to reallocate.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
