[RESEND PATCH] media: siano: fix memory leak of debugfs members in smsdvb_hotplug

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When dvb_create_media_graph fails, the debugfs kept inside client should
be released. However, the current implementation does not release them.

Fix this by adding a new goto label to call smsdvb_debugfs_release.
