From ed5c2f5fd10dda07263f79f338a512c0f49f76f5 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Mon, 15 Aug 2022 10:02:30 +0200 Subject: i2c: Make remove callback return void MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The value returned by an i2c 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.
