From 2dd8ba921d570fcd016f8038c63fa9668892d16b Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Sun, 19 Feb 2012 14:50:12 -0800 Subject: [PATCH] PCI: Fix device class print out Found debug print of class is shifted. | pci 0000:f8:15.2: [8086:2b56] type 0 class 0x000600 Code is trying to print class with 6 digits, but use shifted class with 4 digits valid value as variable. Change to original dev->class directly. Also remove not needed calculating of local variable class, because it will be updated after pci_fixup_device(pci_fixup_early...) Also unify type print out when class and header is not matched.
