| Subject: bt8xx: fix memory leak |
| |
| From: Sudip Mukherjee <sudipm.mukherjee@gmail.com> |
| |
| |
| [ 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. |
