I was testing the polling mode txgbe_i2c_dw_xfer_quirk() on a HW where the i2c-designware has interrupt connected and shared with other device. I noticed there is a bogus interrupt for each transfer. Reason for this that both polling mode functions call the i2c_dw_xfer_init() which enable interrupts then followed by immediate disable by the same polling mode functions. This is enough to trigger TX_EMPTY interrupt. Fix this by introducing a __i2c_dw_write_intr_mask() helper that unmasks interrupts conditionally and use it in i2c_dw_xfer_init().
