In icom, there is an ICOM_PORT macro to perform upcasts from struct uart_port to struct icom_port. It's not completely safe and it works only because the first member of icom_port is uart_port. Nowadays, we use container_of for such an upcast instead. So introduce a helper (to_icom_port()) with container_of in it and convert all the ICOM_PORT users to the new helper. Apart from the code and type safety, it's also clear what icom_port (the variable) is. Unlike with the old ICOM_PORT (the macro with the cast).

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.
