Subject: [PATCH v2 1/2] eeprom: at25: Merge "off" and "offset" in at25_ee_write()

Since commit 01973a01f9ec34b7 ("eeprom: at25: remove nvmem regmap
dependency") changed the type of "off" from "loff_t" to "unsigned int",
"off" and "offset" are now the same type, and can be merged into a
single variable.

Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>
---
v2:
  - Merge "off" and "offset" into a single variable instead of just
    killing the cast, as suggested by Arnd.
