Bug#688990: src:linux: Add support for Buffalo Linkstation LS-XHL and LS-CHLv2
Package: src:linux
Severity: wishlist
Tags: d-i patch
This patch add new hardware support for the Buffalo Linkstation LS-XHL and
LS-CHLv2. Both systems are supported by the upstream linux kernel as per
commit 4aff38a3db1f63494812834f1fbbdb1f00579c66. While the upstream support
is device tree based, this patch uses the old fashioned machine setup.
