From 0af72df267f2ed865c71a69fb2811ea6fa4736dc Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 6 Dec 2016 18:18:30 +0100 Subject: [PATCH] staging: slicoss: remove the staging driver A "real" driver for this hardware has now landed in the networking tree, so remove this old staging driver so that we don't have multiple drivers for the same hardware, and so people don't waste their time trying to clean up this old code.
