    target/pscsi: Fix bug with REPORT_LUNs handling for SCSI passthrough · 1d2a2cd9
    Nicholas Bellinger authored
    This patch fixes a regression bug in pscsi_transport_complete() callback
    code where *pt was being NULL dereferenced during REPORT_LUNS handling,
    that was introduced with the spc/sbc refactoring in:
    
    commit 1fd032ee

        target: move code for CDB emulation
    
    As this is a special case for pscsi_parse_cdb() to call spc_parse_cdb() to
    allow TCM to handle REPORT_LUN emulation, pscsi_plugin_task will have not
    been allocated..
    
    So now in pscsi_transport_complete() just check for existence of *pt and
    return for this special case.
