ide: fix IDE ACPI regression breaking suspend
Commit 4dde4492d850a4c9bcaa92e5bd7f4eebe3e2f5ab ("ide: make drive->id an union (take 2)") accidentally introduced an IDE ACPI regression which at least on some machines confuses ACPI and breaks suspend. Fix it. Fixes kernel.org bug #12279: http://bugzilla.kernel.org/show_bug.cgi?id=12279 [ Sorry about the bug (IDE ACPI is not used by default so it managed to slip in). Still it is kind of surprising that the bug breaks suspend as it shouldn't impact anything except IDE ACPI (it seems that it uncovered either some ACPI/PM deficiency or a BIOS bug). ] Reported-and-bisected-by: David Roka <roka@dawid.hu> Tested-by: David Roka <roka@dawid.hu> Cc: Rafael J.
