From 0aaa0b5f84a0908fb2de30e8fea10811b154bf56 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Fri, 3 Jun 2022 23:07:49 +0200 Subject: [PATCH] mtd: lpddr2_nvm: Warn about failure to unregister mtd device MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit mtd_device_unregister() shouldn't fail. Wail loudly if it does anyhow. This matches how other drivers (e.g. nand/raw/nandsim.c) use mtd_device_unregister(). By returning 0 in the platform remove callback a generic error message by the device core is suppressed, nothing else changes. This is a preparation for making platform remove callbacks return void.
