From e1347bd4abfb3eaee8bbdc9089b64b249a7639b6 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Wed, 4 May 2022 20:31:31 +0200 Subject: leds: is31fl32xx: Improve error reporting in .remove() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Returning an error value in an i2c remove callback results in a generic error message being emitted by the i2c core, but otherwise it doesn't make a difference. The device goes away anyhow and the devm cleanups are called. So instead of triggering the generic i2c error message, emit a more helpful message if a problem occurs and return 0 to suppress the generic message. This patch is a preparation for making i2c remove callbacks return void.
