Subject: [PATCH] media: platform: xilinx: fix error return code of xvip_graph_init()
Date: Fri,  5 Mar 2021 01:48:19 -0800	[thread overview]
Message-ID: <20210305094819.13685-1-baijiaju1990@gmail.com> (raw)

When the list of xdev->notifier.asd_list is empty, no error return code
of xvip_graph_init() is assigned.
To fix this bug, ret is assigned with -ENOENT as error return code.
