[PATCH] ata: read ->revision before dropping pci_device reference

2018-11-27 Thread Pan Bian
pci_device->revision is read after dropping pci_device reference via pci_dev_put, which may result in use-after-free bugs. To fix this, the patch reads ->revision before dropping reference. Signed-off-by: Pan Bian --- drivers/ata/pata_sis.c | 4 +++- drivers/ata/pata_sl82c105.c | 4 +++- 2
