Add a polling mechanism that will keep the driver operational even in absence of physical IRQ connection. If IRQ line is detected, the driver will continue working as usual, in case of missing IRQ line it will fallback to the polling mechanism introduced in this change. This will support users which choose not to connect an IRQ line as it is not critical to part's operation.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
