From f8fce8318366ad4a85aba7a6c9fca900876b01f9 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Date: Fri, 10 Mar 2023 23:41:24 +0100 Subject: bus: fsl-mc: dprc: Push down error message from fsl_mc_driver_remove() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The error message emitted in fsl_mc_driver_remove() is very generic. Replace it by a message that mentions the reason for the failure. Returning zero instead of a negative value has no side effect apart from suppressing the generic error message. The first if condition in dprc_remove() can never be true, as this would prevent successful probing of the device and then .remove wasn't called. So this can just be dropped.
