Commit Message

Sergei Shtylyov June 5, 2013, 9:12 p.m. UTC 
From: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com>

Remove all the duplicate definitions of sh_eth_set_duplex() under  different
#ifdef's, leaving only one outside the #ifdef's. We have to annotate it with
'__maybe_unused' since it's called not from all SoC #ifdef blocks.

Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com>
[Sergei: annotated sh_eth_set_duplex() as '__maybe_unused', added the changelog,
reworded the subject, changing the prefix.]

- refreshed the patch;
- added the changelog;
- reworded the subject, changing the prefix.

Changes in version 3:
