| Subject: memory: mtk-smi: fix device leak on larb probe |
| |
| From: Johan Hovold <johan@kernel.org> |
| |
| [ Upstream commit 9dae65913b32d05dbc8ff4b8a6bf04a0e49a8eb6 ] |
| |
| Make sure to drop the reference taken when looking up the SMI device |
| during larb probe on late probe failure (e.g. probe deferral) and on |
| driver unbind. |
| |
| Fixes: cc8bbe1a8312 ("memory: mediatek: Add SMI driver") |
| Fixes: 038ae37c510f ("memory: mtk-smi: add missing put_device() call in mtk_smi_device_link_common") |
