From 7c8f821e5dde39dd507925168cd38b1e3d9d46d5 Mon Sep 17 00:00:00 2001 From: Ismael Luceno Cortes Date: Thu, 7 Mar 2019 18:00:54 +0000 Subject: [PATCH] i2c: rcar_i2c: Set the slave address from rcar_i2c_xfer It needs to be done for both reads and writes, so do it at rcar_i2c_xfer to avoid duplication.
