For many places in the spi drivers, using the new `spi_transfer_delay` helper is straightforward. It's just replacing: ``` if (t->delay_usecs) udelay(t->delay_usecs); ``` with `spi_transfer_delay(t)` which handles both `delay_usecs` and the new `delay` field. This change replaces in all places (in the spi drivers) where this change is simple.
