    Subject[PATCH 4.19 43/54] pcmcia: i82092: fix a null pointer dereference bug
    Date
    From: Zheyu Ma <zheyuma97@gmail.com>

    commit e39cdacf2f664b09029e7c1eb354c91a20c367af upstream.

    During the driver loading process, the 'dev' field was not assigned, but
    the 'dev' field was referenced in the subsequent 'i82092aa_set_mem_map'
    function.
