Arun Ramadoss ef1100ef20 net: dsa: microchip: Added the condition for scheduling ksz_mib_read_work ... When the ksz module is installed and removed using rmmod, kernel crashes with null pointer dereferrence error. During rmmod, ksz_switch_remove function tries to cancel the mib_read_workqueue using cancel_delayed_work_sync routine and unregister switch from dsa. During dsa_unregister_switch it calls ksz_mac_link_down, which in turn reschedules the workqueue since mib_interval is non-zero. Due to which queue executed after mib_interval and it tries to access dp->slave. But the slave is unregistered in the ksz_switch_remove function. Hence kernel crashes. To avoid this crash, before canceling the workqueue, resetted the mib_interval to 0. v1 -> v2: -Removed the if condition in ksz_mib_read_work Fixes: 469b390e1b ("net: dsa: microchip: use delayed_work instead of timer + work") Signed-off-by: Arun Ramadoss <arun.ramadoss@microchip.com> Signed-off-by: David S.
