[PATCH v2 0/4] drm/nvdla: Add driver support for NVDLA

[PATCH 1/3] dma-buf/sync_file: cleanup fence merging a bit

by Christian König

krealloc_array() ignores attempts to reduce the array size, so the attempt to save memory is completely pointless here. Also move testing for the no fence case into sync_file_set_fence(), this way we don't even touch the fence array when we don't have any fences.

[PATCH 1/4] drm/etnaviv: Use scheduler dependency handling

by Daniel Vetter

We need to pull the drm_sched_job_init much earlier, but that's very minor surgery. v2: Actually fix up cleanup paths by calling drm_sched_job_init, which I wanted to to in the previous round (and did, for all other drivers). Spotted by Lucas. v3: Rebase over renamed functions to add dependencies. v4: Rebase over patches from Christian. v5: More rebasing over work from Christian.

[PATCH] dma-buf: add the name field to the table header

by Yuanzheng Song

'cat /sys/kernel/debug/dma_buf/bufinfo' will print the Dma-buf Objects' information when the CONFIG_DEBUG_FS=y. However, the printed table header information does not contain the name field. So we need to add the name field to the table header and use the '<none>' to replace the empty buf_obj->name.

[PATCH 1/3] mtd: rawnand: cadence: fix possible null-ptr-deref in cadence_nand_dt_probe()

It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref.

[PATCH] dma-buf: remove trace_dma_fence_emit

by Christian König

There was never any significant difference between trace_dma_fence_emit() and trace_dma_fence_init() and the only place where it would made a significant difference was never implemented. So remove trace_dma_fence_emit() since we have an repeating issue that people are trying to use it for visualization and are surprised that it actually doesn't work for most drivers.
