[PATCH 4.4 17/25] pcmcia: i82092: fix a null pointer dereference bug

[Greg Kroah-Hartman]

From: Zheyu Ma <zheyuma97@xxxxxxxxx>

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.
