Subject: [PATCH v2 1/2] eeprom: at25: Merge "off" and "offset" in at25_ee_write()
Date:   Fri, 18 Jan 2019 15:05:24 +0100
Message-Id: <20190118140525.29189-2-geert+renesas@glider.be>
In-Reply-To: <20190118140525.29189-1-geert+renesas@glider.be>
References: <20190118140525.29189-1-geert+renesas@glider.be>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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@glider.be>

v2:
  - Merge "off" and "offset" into a single variable instead of just
    killing the cast, as suggested by Arnd.
