[PATCH] pci: initialize struct pci_dev.error_state
The pci channel state is currently uninitialized, thus there are two ways of indicating that "everything's OK": 0 and 1. This is a bit of a burden. If a devce driver wants to check if the pci channel is in a working or a disconnected state, the driver writer must perform checks similar to if((pdev->error_state != 0) && (pdev->error_state != pci_channel_io_normal)) { whatever(); } which is rather akward. The first check is needed because stuct pci_dev is inited to all-zeros. The scond is needed because the error recovery will set the state to pci_channel_io_normal (which is not zero). This patch fixes this awkwardness.
