Subject: [PATCH] drm/vkms: Remove useless call to drm_connector_register()
Date: Sun, 10 Mar 2019 18:22:41 -0300 [thread overview]
Message-ID: <20190310212241.4fsqejz5rlnp7m2k@smtp.gmail.com> (raw)
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.
Therefore, this commit removes the drm_connector_register() from
vkms_output_init().
