From 989bb924c464f08ddac9c8ccb4bf6babbb9083f3 Mon Sep 17 00:00:00 2001 From: Beniamino Galvani Date: Sun, 26 Nov 2017 17:40:56 +0100 Subject: [PATCH] i2c: meson: fix return codes on error Change meson_i2c_xfer_msg() to return -EREMOTEIO in case of NACK, as done by other drivers. Also, don't change the return error in meson_i2c_xfer().
