Subject: [PATCH] media: dvbdev: Fix memleak in dvb_register_device
Date: Mon, 24 Aug 2020 20:27:46 +0800 [thread overview]
Message-ID: <20200824122749.27147-1-dinghao.liu@zju.edu.cn> (raw)
When device_create() fails, dvbdev and dvbdevfops should
be freed just like when dvb_register_media_device() fails.
