[PATCH] arcnet: remove check for CONFIG_SA1100_CT6001

From: Paul Bolle
Date: Tue May 27 2014 - 15:53:52 EST


A check for CONFIG_SA1100_CT6001 was added in v2.6.11. But the related
Kconfig symbol was never added to the tree. Remove this check and do
some related cleaning up.

Entirely untested.

arcnet was new for me (as are a lot of things). So I did a rather wide
search of Red Hat's (and Fedora's) bugzilla. I got no hit that suggested
anyone, ever, used arcnet. Is there any indication that people still
care about arcnet?
