V4L/DVB (13646): sh_mobile_ceu_camera: do not mark host occupied, when adding a client fails
Currently, if resetting the host interface, when adding a new client, fails, a negative error code is returned, but the host is still marked as occupied. Fix this bug. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
