[PATCH] ahci: ignore PORT_IRQ_IF_ERR on JMB controllers
JMicron AHCI controllers set PORT_IRQ_IF_ERR on device errors. The
IRQ status bit indicates interface error or protocol mismatch and ahci
driver interprets it into AC_ERR_ATA_BUS. So, whenever an ATAPI
device raises check condition, ahci interprets it as ATA bus error and
thus resets it which, in turn, raises check condition thus creating a
reset loop and rendering the device unuseable.
This patch makes JMB controllers ignore PORT_IRQ_IF_ERR when
interpreting error condition.
