[PATCH 1/2] dma-buf/sync_file: hold reference to fence when creating sync_file

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan at collabora.co.uk>

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.
