Can a static source code analysis tool like the software "http://smatch.sourceforge.net/";
detect that such a variable is not read by this function implementation so far?
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/tree/drivers/net/ethernet/freescale/gianfar_ethtool.c?id=b75ec3af27bf011a760e2f44eb25a99b6fbb0fb3#n850
Does this place indicate an unwanted value assignment as a leftover,
or are there any other actions missing?
