From 9db34ee64ce492c7ede3555ed690c8253d9935e4 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Thu, 19 Nov 2020 17:16:03 +0100 Subject: spi: Use bus_type functions for probe, remove and shutdown MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The eventual goal is to get rid of the callbacks in struct device_driver. Other than not using driver callbacks there should be no side effect of this patch.
