For memory allocation functions that fail with a NULL return value, it is preferred to use the (!x) test in place of (x == NULL). Changes in atomisp2/css2400/sh_css.c were done by hand. Done with the help of the following cocci script: @@ type T; T* p; statement s,s1; @@ p = \(devm_kzalloc\|devm_ioremap\|usb_alloc_urb\|alloc_netdev\|dev_alloc_skb\| kmalloc\|kmalloc_array\|kzalloc\|kcalloc\|kmem_cache_alloc\|kmem_cache_zalloc\| kmem_cache_alloc_node\|kmalloc_node\|kzalloc_node\|devm_kzalloc\)(...) ...when != p if ( - p == NULL + !p ) s else s1 -- Changes in v3: Rebase changes over atomisp-next branch of the media tree Changes in atomisp2/css2400/sh_css.c were done by hand, the above script was not able to match the pattern if (a->b != null).

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.
