Subject: [PATCH v3] mfd: madera-i2c: Simplify probe()
Date:   Thu, 31 Aug 2023 20:17:17 +0100
Message-Id: <20230831191718.75509-1-biju.das.jz@bp.renesas.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Simplify probe() by replacing of_device_get_match_data() and ID lookup for
retrieving match data by i2c_get_match_data().

Note:
 This patch is only compile tested.

v2->v3:
 * Used uintptr_t for enum casting.
v1->v2:
 * Added Ack tag from Charles Keepax.
 * Dropped blank line before switch statement.
