The timer expiry routine `jr3_pci_poll_dev()` checks for expiry by checking whether the absolute value of `jiffies` (stored in local variable `now`) is greater than the expected expiry time in jiffy units. This will fail when `jiffies` wraps around. Also, it seems to make sense to handle the expiry one jiffy earlier than the current test. Use `time_after_eq()` to check for expiry.

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.
