Subject: [RESEND PATCH] drm/mipi-dsi: Fix error handling in mipi_dsi_device_register_full
Date: Wed, 1 Jun 2022 16:40:24 +0400 [thread overview]
Message-ID: <20220601124024.10137-1-linmq006@gmail.com> (raw)
In mipi_dsi_device_alloc(), it calls device_initialize(&dsi->dev);
We need to use put_device() instead freeing directly.
Fixes: 068a002 ("drm: Add MIPI DSI bus support")
