[PATCH 1/1] ahci: Do not receive interrupts sent by dummy ports

2014-04-17 Thread Alexander Gordeev
In multiple MSI mode all AHCI ports (including dummy) get assigned separate MSI vectors and (as result of execution pci_enable_msi_exact() function) separate IRQ numbers, (mapped to the MSI vectors). Therefore, although interrupts from dummy ports are not desired they are still enabled. We do not
