If 'find_device()' finds something, we set '*error_out' and we should
return an error. However, 'err' is known to be 0 at this point.
Explicitly return -EINVAL instead.
While at it, remove the initialization of 'err' at the beginning of the
function and also explicitly return an error code if the first check
fails.

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.
