Maciej Sosnowski 8b794b141c I/OAT: fail initialization on zero channels detection
On some systems with I/OAT ver.2 when DCA is disabled in BIOS
situations have been observed
that zero DMA channels are detected instead of four.
To avoid kernel panic driver should fail gracefully with appropriate message.
