4.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: "Michael S. Tsirkin" <mst@xxxxxxxxxx> [ Upstream commit 75993300d008f418ee2569a632185fc1d7d50674 ] ANY_LAYOUT is a compatibility feature. It's implied for VERSION_1 devices, and non-transitional devices might not offer it. Change code to behave accordingly. Signed-off-by: Michael S.
