Audit trail is showing double entries for Payment and Deposit

The audit trail report is showing double entries for Payment and Deposit for Customer/Suppllier entries.

If the payment/deposits are made to Misc. than there is single entry posting in audit trail, but if we select customer/supplier it loads add_audit_trail therefore i have added the following in

1: For customer trans
/sales/includes/db/cust_trans_db.inc

Under write_customer_trans function i have replaced
    if ($trans_type != ST_JOURNAL) // skip for journal entries

with

    if ($trans_type != ST_JOURNAL && $trans_type != ST_BANKDEPOSIT && $trans_type != ST_BANKPAYMENT) // skip for journal entries

2. For Supplier trans
and in /purchasing/includes/db/supp_trans_db.inc
under write_supp_trans function i have added this line

    if ($type != ST_JOURNAL && $type != ST_BANKDEPOSIT && $type != ST_BANKPAYMENT // skip for journal entries
above
    add_audit_trail($type, $trans_no, $date_,"Added",$amount);

This fixes the double posting of the same transactions in audit_trail table
