Subject: [PATCH v2 0/2] eeprom: at25: SPI transfer improvements

	Hi all,

This patch series contains two improvements for the AT25 SPI EEPROM
driver, related to SPI transfers.

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.

Thanks!

  eeprom: at25: Merge "off" and "offset" in at25_ee_write()
  eeprom: at25: Use spi_message_init_with_transfers() instead of open
    coding
