cross-tree: phase out dma_zalloc_coherent()

2019-01-08T12:58:37Z

We already need to zero out memory for dma_alloc_coherent(), as such using dma_zalloc_coherent() is superflous. Phase it out. This change was generated with the following Coccinelle SmPL patch: @ replace_dma_zalloc_coherent @ expression dev, size, data, handle, flags; @@ -dma_zalloc_coherent(dev, size, handle, flags) +dma_alloc_coherent(dev, size, handle, flags) Suggested-by: Christoph Hellwig Signed-off-by: Luis Chamberlain [hch: re-ran the script on the latest tree] Signed-off-by: Christoph Hellwig

media: mtk-vcodec: Remove VA from encoder frame buffers

2018-12-03T19:29:14Z

The encoder driver has no need to do any CPU access to the source frame buffers. Use a separate structure for holding DMA addresses and sizes for those and remove, so we do not end up introducing any erroneous dereferences of those VAs. This fixes DMA-buf import from exporters that do not provide contiguous kernel mappings, which includes the MTK DRM driver.

media: mtk-vcodec: Release device nodes in mtk_vcodec_init_enc_pm()

2018-11-23T09:34:10Z

of_parse_phandle() returns the device node with refcount incremented. There are two nodes that are used temporary in mtk_vcodec_init_enc_pm(), but their refcounts are not decremented. The patch adds one of_node_put() and fixes returning error codes. Found by Linux Driver Verification project (linuxtesting.org).

media: mtk_vcodec_util: Use dma_zalloc_coherent to replace dma_alloc_coherent + memset

2018-09-12T14:48:59Z

dma_zalloc_coherent has implemented the dma_alloc_coherent() + memset(), We prefer to dma_zalloc_coherent instead of open-codeing. Signed-off-by: zhong jiang Signed-off-by: Mauro Carvalho Chehab

media: use strscpy() instead of strlcpy()

2018-09-11T17:32:17Z

The implementation of strscpy() is more robust and safer. That's now the recommended way to copy NUL terminated strings. Signed-off-by: Mauro Carvalho Chehab Reviewed-by: Kees Cook Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: mtk-vcodec: Always signal source change event on format change

2018-02-26T12:41:36Z

Currently the driver signals the source change event only in case of a midstream resolution change, however the initial format detection is also defined as a source change by the V4L2 codec API specification. Fix this by signaling the event after the initial header is parsed as well. Signed-off-by: Tomasz Figa Reviewed-by: Wu-Cheng Li Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
