6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Saurav Kashyap <skashyap@xxxxxxxxxxx> commit e288285d47784fdcf7c81be56df7d65c6f10c58b upstream. Coverity scan reported potential risk of double free of the pointer ha->vp_map. ha->vp_map was freed in qla2x00_mem_alloc(), and again freed in function qla2x00_mem_free(ha). Assign NULL to vp_map and kfree take care of NULL.
