Jason Ekstrand 41f45e91c9 dma-buf/sync_file: Don't leak fences on merge failure ... commit ffe000217c5068c5da07ccb1c0f8cce7ad767435 upstream. Each add_fence() call does a dma_fence_get() on the relevant fence. In the error path, we weren't calling dma_fence_put() so all those fences got leaked. Also, in the krealloc_array failure case, we weren't freeing the fences array. Instead, ensure that i and fences are always zero-initialized and dma_fence_put() all the fences and kfree(fences) on every error path.
