Currently the for-loop in ksz8_port_init_cnt is causing a static analysis infinite loop warning with the comparison of mib->cnt_ptr < dev->reg_mib_cnt. This occurs because mib->cnt_ptr is a u8 and dev->reg_mib_cnt is an int and the analyzer determines that mib->cnt_ptr potentially can wrap around to zero if the value in dev->reg_mib_cnt is > 255. However, this value is never this large, it is always less than 256 so make reg_mib_cnt a u8.

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.
