Subject: [PATCH] drm/mediatek: add missing put_device() call in mtk_hdmi_dt_parse_pdata()
Date: Fri, 11 Sep 2020 19:21:51 +0800 [thread overview]
Message-ID: <20200911112151.3220469-1-yukuai3@huawei.com> (raw)
if of_find_device_by_node() succeed, mtk_drm_kms_init() doesn't have
a corresponding put_device(). Thus add jump target to fix the exception
handling for this function implementation.
Fixes: 8f83f26891e1 ("drm/mediatek: Add HDMI support")
