From 9da32ba64d59d577297bf766a3f12753ebef5712 Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Fri, 13 Oct 2017 00:04:47 +0200 Subject: rtc: abx80x: solve race condition There is a race condition that can happen if abx80x_probe() fails after the rtc registration succeeded. Solve that by moving the registration at the end of the probe function.
