According to Whiskey Cove PMIC spec, bit 7 of GPIOIRQ0_REG belongs to battery IO. So we should skip this bit when checking for GPIO IRQ pending status. Otherwise, wcove_gpio_irq_handler() might go into the infinite loop until IRQ "pending" status becomes 0. This patch fixes this issue.

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.
