    net: dp83640: Avoid NULL pointer dereference. · db9d8b29
    Richard Cochran 提交于
    The function, skb_complete_tx_timestamp(), used to allow passing in a
    NULL pointer for the time stamps, but that was changed in commit
    62bccb8c ("net-timestamp: Make the
    clone operation stand-alone from phy timestamping"), and the existing
    call sites, all of which are in the dp83640 driver, were fixed up.
    
    Even though the kernel-doc was subsequently updated in commit
    7a76a021 ("net-timestamp: Update
    skb_complete_tx_timestamp comment"), still a bug fix from Manfred
    Rudigier came into the driver using the old semantics.  Probably
    Manfred derived that patch from an older kernel version.
    
    This fix should be applied to the stable trees as well.
