    Subject[PATCH 4.19 559/639] net: sonic: replace dev_kfree_skb in sonic_send_packet
    Date
    From: Mao Wenan <maowenan@huawei.com>

    [ Upstream commit 49f6c90bf6805948b597eabb499e500a47cf24be ]

    sonic_send_packet will be processed in irq or non-irq
    context, so it would better use dev_kfree_skb_any
    instead of dev_kfree_skb.

    Fixes: d9fb9f384292 ("*sonic/natsemi/ns83829: Move the National Semi-conductor drivers")
