commit21698fd579upstream. In the original code before181bf1e815the loop was continuing until it finds the first matching superios[i].io and p->base. But after181bf1e815the logic changed and the loop now returns the pointer to the first mismatched array element which is then used in get_superio_dma() and get_superio_irq() and thus returning the wrong value. Fix the condition so that it now returns the correct pointer.

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.
