PCI: pcie, aer: change error print format
Use dev_printk like format. Sample (real machine + dummy error injected by aer-inject): - Before: +------ PCI-Express Device Error ------+ Error Severity : Corrected PCIE Bus Error type : Data Link Layer Bad TLP : Receiver ID : 2800 VendorID=8086h, DeviceID=1096h, Bus=28h, Device=00h, Function=00h +------ PCI-Express Device Error ------+ Error Severity : Corrected PCIE Bus Error type : Data Link Layer Bad TLP : Bad DLLP : Receiver ID : 2801 VendorID=8086h, DeviceID=1096h, Bus=28h, Device=00h, Function=01h Error of this Agent(2801) is reported first - After: pcieport-driver 0000:00:02.0: AER: Multiple Corrected error received: id=2801 e1000e 0000:28:00.0: PCIE Bus Error: severity=Corrected, type=Data Link Layer, id=2800(Receiver ID) e1000e 0000:28:00.0: device [8086:1096] error status/mask=00000040/00000000 e1000e 0000:28:00.0: [ 6] Bad TLP e1000e 0000:28:00.1: PCIE Bus Error: severity=Corrected, type=Data Link Layer, id=2801(Receiver ID) e1000e 0000:28:00.1: device [8086:1096] error status/mask=000000c0/00000000 e1000e 0000:28:00.1: [ 6] Bad TLP e1000e 0000:28:00.1: [ 7] Bad DLLP e1000e 0000:28:00.1: Error of this Agent(2801) is reported first Signed-off-by: Hidetoshi Seto <seto.hidetoshi@jp.fujitsu.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
