When an interrupt occurs on an MCP23S08 chip, the INTF register will only contain one bit as causing the interrupt. If more than two pins change at the same time on the chip, this causes one of the pins to not be reported. This patch fixes the logic for checking if a pin has changed, so that multiple pins will always cause more than one change.

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.
