In the APi wlansap_roam_callback, under switch
case of roam result eCSR_ROAM_RESULT_INFRA_ASSOCIATION_IND,
the driver passes csr_roam_info in
wlansap_roam_process_infra_assoc_ind without a NULL check for
the same, which may cause pointer dereference.
Fix is to call wlansap_roam_process_infra_assoc_ind only if
csr_roam_info is valid
