From a0386bba70934d42f586eaf68b21d5eeaffa7bd0 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Sun, 23 Jan 2022 18:52:01 +0100 Subject: spi: make remove callback a void function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.
