[ Upstream commit c6213eb1ae ]
This fixes klockworks warnings: Pointer 'dev' returned from call to
function 'bus_find_device' at line 179 may be NULL and will be dereferenced
at line 181.
cpsw-phy-sel.c:179: 'dev' is assigned the return value from function 'bus_find_device'.
bus.c:342: 'bus_find_device' explicitly returns a NULL value.
cpsw-phy-sel.c:181: 'dev' is dereferenced by passing argument 1 to function 'dev_get_drvdata'.
device.h:1024: 'dev' is passed to function 'dev_get_drvdata'.
device.h:1026: 'dev' is explicitly dereferenced.

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.
