From f7e8466a045c690002c1926e695ae312dd73bb4a Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 28 Apr 2008 16:33:59 -0600 Subject: PNPACPI: pnpacpi_encode_ext_irq() wrongly set "irq" instead of "extended_irq" pnpacpi_encode_ext_irq() should set resource->data.extended_irq, not resource->data.irq. This has been wrong since at least 2.6.12. I haven't seen any bug reports, but it's clearly incorrect.

Passing only the pnp_dev * reduces the possibility for error in the caller and removes the pnp_resource_table implementation detail from the interface. Even though pnp_init_resource_table() is exported, I did not export pnp_init_resources() because it is used only by the PNP core.
