From c31d32ba580d2f361e6169c093fdf624e5851925 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Sun, 7 Feb 2021 22:55:55 +0100 Subject: ipack: Fail earlier for drivers without probe function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A driver without a probe function isn't useful as it can never be used. Let registering such a driver fail already instead of failing every binding. This is only cosmetic as there is no ipack driver without a probe function.
