I have shown my change in comment 39, copy to here again
static void advance_transaction(struct acpi_ec *ec, u8 status)
{
unsigned long flags;
struct transaction *t = ec->curr;
spin_lock_irqsave(&ec->lock, flags);
if (!t)
goto unlock;
if (t->wlen > t->wi) {
//bxudbg>>>
if (t->wi == 0) {
if (((status & ACPI_EC_FLAG_IBF) == 0) && ((status &
ACPI_EC_FLAG_CMD) == 0x08))
acpi_ec_write_data(ec,t->wdata[t->wi++]);
else
goto err;
}
else {
if (((status & ACPI_EC_FLAG_IBF) == 0) && ((status &
ACPI_EC_FLAG_CMD) == 0))
acpi_ec_write_data(ec,t->wdata[t->wi++]);
else
goto err;
}
//bxudbg<<<
// if ((status & ACPI_EC_FLAG_IBF) == 0)
// acpi_ec_write_data(ec,
