From: Paul Gortmaker Date: Thu, 10 May 2012 19:50:52 +0000 (-0400) Subject: s390: delete any traces of token ring support X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1abd2296b4a1ee7b6a883541c3ede52042a09521;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git s390: delete any traces of token ring support The token ring support is going away from the core kernel. Divorce the S390 drivers from it in advance.
