+Subject: pcmcia: i82092: fix a null pointer dereference bug
+
+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.
