When a USB ethernet device is halted, the device driver is removed. When this happens the uclass private memory is freed and uclass_priv is set to NULL. This causes a data abort when uclass_priv->state is then set to ETH_STATE_PASSIVE.
Fix it by checking if uclass_priv is NULL before setting uclass_priv->state Signed-off-by: Jean-Jacques Hiblot <jjhib...@ti.com> Acked-by: Joe Hershberger <joe.hershber...@ni.com> --- Changes in v3: None Changes in v2: None net/eth-uclass.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/net/eth-uclass.c b/net/eth-uclass.c index e4b4922..3a5217a 100644 --- a/net/eth-uclass.c +++ b/net/eth-uclass.c @@ -312,7 +312,8 @@ void eth_halt(void) eth_get_ops(current)->stop(current); priv = current->uclass_priv; - priv->state = ETH_STATE_PASSIVE; + if (priv) + priv->state = ETH_STATE_PASSIVE; } int eth_is_active(struct udevice *dev) -- 2.7.4 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
