[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

From: Sudip Mukherjee <sudipm.mukherjee@xxxxxxxxx>


[ Upstream commit 6792eb0cf9310ec240b7e7c9bfa86dff4c758c68 ]

If dvb_attach() fails then we were just printing an error message and
exiting but the memory allocated to state was not released.
