| |
The extra calls to video_device_release() are a bug, we free these after the goto.
Fixes: c974c436eaf4 ('s5p-mfc: Fix race between s5p_mfc_probe() and s5p_mfc_open()') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> --- This code would be easier to understand if it didn't use "come from" style label names so that "goto release_dec;" would release dec etc instead of "goto register_dec;"
