[PATCH 0/2] blackfin: Drop non-functional DSA code

[Florian Fainelli]

Hi David,

I sent those many months ago in the hope that the bfin-linux people
would pick those patches but nobody seems to be responding, can you
queue those via net-next since this affects DSA?

Thanks!

[PATCH 1/2] blackfin: tcm-bf518: Remove dsa.h inclusion

[Florian Fainelli]

Nothing in that file uses definitions from that header, so just get rid of it.

[PATCH 2/2] blackfin: ezbrd: Remove non-functional DSA/KSZ8893M code

[Florian Fainelli]

There is no in tree driver for the KSZ8893M switch driver, so just get rid of
the code in that board file.

Ok, if they aren't responding what can we do.  Probably should update
the MAINTAINERS file to reflect this...

Series applied to net-next, thanks.
