From: Gustavo Padovan Date: Wed, 19 Oct 2016 17:48:32 +0000 (-0200) Subject: dma-buf/sync_file: hold reference to fence when creating sync_file X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=30cd85dd6edc86ea8d8589efb813f1fad41ef233;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git dma-buf/sync_file: hold reference to fence when creating sync_file 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.
