From 1ae752bf390c84250b702bd7d983c94d6eda42e2 Mon Sep 17 00:00:00 2001 From: Rodrigo Siqueira Date: Fri, 15 Mar 2019 13:11:42 -0300 Subject: [PATCH] drm/vkms: Remove useless call to drm_connector_register/unregister() The function vkms_output_init() is invoked during the module initialization, and it handles the creation/configuration of the vkms essential elements (e.g., connectors, encoder, etc). Among the initializations, this function tries to initialize a connector and register it by calling drm_connector_register(). However, inside the drm_connector_register(), at the beginning of this function there is the following validation: if (!connector->dev->registered) return 0; In this sense, invoke drm_connector_register() after initializing the connector has no effect because the register field is false. The connector register happens when drm_dev_register() is invoked; the same issue exists with drm_connector_unregister(). Therefore, this commit removes the unnecessary call to drm_connector_register() and drm_connector_unregister().
