Subject: dma-buf/sync_file: hold reference to fence when creating sync_file
From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
commit 30cd85dd6edc86ea8d8589efb813f1fad41ef233 upstream.
fence referencing was out of balance. It was not taking any ref to the
fence at creating time, but it was putting a reference when freeing the
sync file.
This patch fixes the balancing issue by getting a reference for the fence
when creating the sync_file.
