Subject: [PATCH v2 1/2] iio: dac: ti-dac5571: Use i2c_get_match_data()
Date: Fri, 18 Aug 2023 18:39:06 +0100	[thread overview]
Message-ID: <20230818173907.323640-2-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20230818173907.323640-1-biju.das.jz@bp.renesas.com>

Replace device_get_match_data() and id lookup for retrieving match data
by i2c_get_match_data() by converting enum->pointer for data in the
match table.
