From 68c624f860b30408afde81a91b4c9df3e915ed85 Mon Sep 17 00:00:00 2001 From: Biju Das Date: Mon, 17 Jul 2023 13:40:58 +0100 Subject: [PATCH] rtc: pcf85063: Simplify probe() The pcf85063_ids[].driver_data could store a pointer to the config, like for DT-based matching, making I2C and DT-based matching more similar. After that, we can simplify the probe() by replacing of_device_get_ match_data() and i2c_match_id() by i2c_get_match_data() as we have similar I2C and DT-based matching table.
