The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'mantis_alloc_buffers()' (mantis_dma.c) GFP_KERNEL can be used because it is called from 'mantis_dma_init()' which is only called from probe functions and no lock is taken in the between. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Link: https://lore.kernel.org/linux-media/20200913145716.361507-1-christophe.jaillet@wanadoo.frSigned-off-by:

Return "0" on line 744 Code was enclosed with #if 0 and thus this variable was not needed. Remove that function altogether.

In the case where the call to lm3554_platform_data_func returns an error there is a memory leak on the error return path of object flash. Fix this by adding an error return path that will free flash and rename labels fail2 to fail3 and fail1 to fail2.

the kAPI for a frontend can use 3 different tuning methods: 1. The hardware tracks internally frequency shifts via its own internal zigzag logic; 2. The hardware has a custom zigzag method, implemented via fe search() ops; 3. The hardware doesn't have any internal zigzag logic. So, the Kernel needs to implement it. Drivers that use the in-kernel software zigzag are required to provide some parameters for the zigzag code to work. Failing to do that will just make the Kernel to tune several times to the very same frequency, delaying the tuning time for no good reason. This is actually a kAPI violation (and an uAPI one, as the frequency shift is exported to the uAPI). Emit a warning on such case, as the driver needs to be fixed.

The VIDIOC_G/S/TRY_EXT_CTRLS documentation has large explanatory texts for some of the fields in a table. This makes it hard to read. Move those text to a new cell spanning the whole width of the table, similar to what was done for struct v4l2_pix_format. This makes it much more readable. Also move the 'ctrl_class' description to below the 'which' description and just mention that it is deprecated and that 'which' should be used instead. Finally remove 'note::' for the V4L2_CTRL_WHICH_DEF_VAL description. It doesn't have to be marked as a note, it's just a simple paragraph. Signed-off-by:
