Function platform_get_irq_byname() returns a negative error code on failure, and a zero or positive number on success. However, in function cpcap_usb_init_irq(), positive IRQ numbers are also taken as error cases. Use "if (irq < 0)" instead of "if (!irq)" to validate the return value of platform_get_irq_byname().

README
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.
