The commitd96febedfd("net: stmmac: arrange Tx tail pointer update to stmmac_flush_tx_descriptors") introduced the following coverity warning:- 1. Unintentional integer overflow (OVERFLOW_BEFORE_WIDEN) overflow_before_widen: Potentially overflowing expression 'tx_q->cur_tx * desc_size' with type 'unsigned int' (32 bits, unsigned) is evaluated using 32-bit arithmetic, and then used in a context that expects an expression of type dma_addr_t (64 bits, unsigned). Fixed this by assigning tx_tail_addr to dma_addr_t type, as dma_addr_t datatype is decided by CONFIG_ARCH_DMA_ADDR_T_64_BIT.

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.
