If a device is removed during EEH processing (either by a driver's handler or as part of recovery), it can lead to a null dereference in eeh_pe_report_edev(). To handle this, skip devices that have been removed. Signed-off-by: Sam Bobroff <sbobroff@linux.ibm.com> --- arch/powerpc/kernel/eeh_driver.c | 4 ++++ 1 file changed, 4 insertions(+)
