From 39eb3cc8ab8a5cb7b0a2b728cb653e58319449e9 Mon Sep 17 00:00:00 2001 From: Corentin Labbe Date: Thu, 2 Apr 2020 09:08:52 +0000 Subject: pinctrl: sunxi: handle probe defferal When checking the logs on my sun8i-a33-olinuxino I saw: sun8i-a23-r-pinctrl 1f02c00.pinctrl: Reset controller missing but this driver was working after. This message is just here because the reset controller was still not probed. So don't say anything if the return code say to wait.
