After inspection made by Markus using Coccinelle software, he observed that we could possibly be triggering a NULL pointer dereference in 2 functions [0]. After discussion in mailing list, it was observed in fact we have two unnecessary checks for NULL pointer, and they were leading to Coccinelle warn. So, instead of reworking the code as proposed by him, we hereby remove the unnecessary checks, and also some unneeded extra lines in the code. These two unnecessary NULL checks were tracked in the call chain as never NULL, so they can be safely removed. No functional changes are intended.

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.
