Function lan743x_phy_init assigns pointer 'netdev' but this is never read and hence it can be removed. The return error code handling can also be cleaned up to remove the variable 'ret'. Function lan743x_phy_link_status_change assigns pointer 'phy' twice and this is never read, so it also can be removed. Finally, function lan743x_tx_napi_poll initializes pointer 'adapter' and then re-assigns the same value into this pointer a little later on so this second assignment is redundant and can be also removed.

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.
