[PATCH v5 1/6] net: sh_eth: remove unnecessary function

[Shimoda, Yoshihiro]

The sh_eth_timer() called mod_timer() for itself.
So, this patch removes the function.

It is not appropriate to submit cleanups and feature additions for the
'net-next' tree at this time.  That is only valid when I open the
net-next tree back up which will be shortly after the merge window
closes.

If you have bug fixes to submit for the 'net' tree, you must split
them off from these cleanups and submit them seperately.

I understood it. The "PATCH 3/6" is a bug fix. So, I will submit it
first for the "net" tree.
After the merge window closes I will submit other patches.
