Subject: [PATCH] detect-virt: use /proc/device-tree
1ff636
1ff636
Kernel doc Documentation/ABI/testing/sysfs-firmware-ofw says that
1ff636
the /proc/device-tree symlink should be used, as opposed to
1ff636
directly accessing /sys/firmware/devicetree/base. The former is
1ff636
ABI, but not the later.

Cherry-picked from: b8f1df82646d2

Resolves: #1207773
