i2c-designware: i2c_dw_xfer_msg: Introduce a local "buf" pointer
While we have a local variable "buf_len" for dev->tx_buf_len, we don't have such local variable for dev->tx_buf pointer. While "buf_len" is restored at first then updated when we start processing a new i2c_msg (determined by STATUS_WRITE_IN_PROGRESS flag), ->tx_buf is different. Such inconsistency makes the code slightly hard to follow. Signed-off-by:Shinya Kuribayashi <shinya.kuribayashi@necel.com> Acked-by:
