    Subject[PATCH 5.13 461/800] ssb: Fix error return code in ssb_bus_scan()
    Date
    From: Zhen Lei <thunder.leizhen@huawei.com>

    [ Upstream commit 77a0989baa427dbd242c5784d05a53ca3d197d43 ]

    Fix to return -EINVAL from the error handling case instead of 0, as done
    elsewhere in this function.

    Fixes: 61e115a56d1a ("[SSB]: add Sonics Silicon Backplane bus support")
