4.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: "Martin K. Petersen" <martin.petersen@xxxxxxxxxx> commit eab6ee1ce3c4678224d70338134f7a02005768cb upstream. Commit 5d3abf8ff67f ("libata: Fall back to unqueued READ LOG EXT if the DMA variant fails") allowed us to fall back to the unqueued READ LOG variant if the queued version failed. However, if the device did not support the page at all we would end up looping due to a merge snafu. Ensure we only take the fallback path once. Signed-off-by: Martin K.
