I'll change the title and commit msg at the next version below:

Fix unintentional integer overflow in multiplying different types

1. Instead of multiplying 2 variable of different types. Change to
assign a value of one variable and then multiply the other variable.

2. Add a int variable for multiplier calculation instead of calculating
different types multiplier with dma_addr_t variable directly.


Thanks!
