Changes compared to v1: - Merge "off" and "offset" into a single variable instead of just killing the cast, as suggested by Arnd, - Add Acked-by, - Dropped "[PATCH 3/3] eeprom: at25: Split writes in two SPI transfers to optimize DMA", as this is better implemented in the SPI controller driver (cfr. e.g. "[v2 PATCH 2/2] spi: sh-msiof: Use DMA if possible", https://lore.kernel.org/linux-renesas-soc/1547803771-9564-2-git-send-email-na-hoan@jinso.co.jp/) Tested on a Renesas Ebisu development board with R-Car E3 using MSIOF and a 25LC040 EEPROM.
