2020-12-03media: rockchip: rkisp1: remove useless debugfs checksDan Carpenter
The debugfs_create_dir() function never returns NULLs so this code will never be executed. It's not intended that callers will check for debugfs errors in the normal case and it's not necessary in this driver, so we can just delete this code.

2020-12-03media: saa7146: switch from 'pci_' to 'dma_' APIChristophe JAILLET
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 'saa7146_pgtable_alloc()' GFP_KERNEL can be used because the callers are either .buf_prepare functions or function that already use GFP_KERNEL (hidden in a 'vmalloc_32()' call). When memory is allocated in 'saa7146_init_one()' GFP_KERNEL can be used because it is probe function and no lock is taken in the between. When memory is allocated in 'saa7146_vv_init()' GFP_KERNEL can be used because this function already uses GFP_KERNEL and no lock is taken in the between. When memory is allocated in 'vbi_workaround()' GFP_KERNEL can be used because it is only called from a .open function. @@ @@ - 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) Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

This reverts commit c90f1178dcac30dee5ddd29ec0513e7589aa866e. The assumption of "Each entry in formats[] table has unique mbus_code" is valid for the RDI entities, but not for the PIX ones.

VP8 in Cedrus shares same engine as H264. Note that it seems necessary to call bitstream parsing functions, to parse frame header, otherwise decoded image is garbage. This is contrary to what is driver supposed to do. However, values are not really used, so this might be acceptable. It's possible that bitstream parsing functions set some internal VPU state, which is later necessary for proper decoding. Biggest suspect is "VP8 probs update" trigger.

On AMD Family 15h (Models 30h-3fh), I/O Memory Management Unit RiSC engine sometimes stalls, requiring a reset. As result, MythTV and w-scan won't scan channels on the AMD Kaveri APU with the Hauppauge QuadHD TV tuner card.

2020-12-02fscrypt: allow deleting files with unsupported encryption policyEric Biggers
Currently it's impossible to delete files that use an unsupported encryption policy, as the kernel will just return an error when performing any operation on the top-level encrypted directory, even just a path lookup into the directory or opening the directory for readdir. More specifically, this occurs in any of the following cases: - The encryption context has an unrecognized version number. Current kernels know about v1 and v2, but there could be more versions in the future. - The encryption context has unrecognized encryption modes (FSCRYPT_MODE_*) or flags (FSCRYPT_POLICY_FLAG_*), an unrecognized combination of modes, or reserved bits set. - The encryption key has been added and the encryption modes are recognized but aren't available in the crypto API -- for example, a directory is encrypted with FSCRYPT_MODE_ADIANTUM but the kernel doesn't have CONFIG_CRYPTO_ADIANTUM enabled. It's desirable to return errors for most operations on files that use an unsupported encryption policy, but the current behavior is too strict. We need to allow enough to delete files, so that people can't be stuck with undeletable files when downgrading kernel versions. That includes allowing directories to be listed and allowing dentries to be looked up. Fix this by modifying the key setup logic to treat an unsupported encryption policy in the same way as "key unavailable" in the cases that are required for a recursive delete to work: preparing for a readdir or a dentry lookup, revalidating a dentry, or checking whether an inode has the same encryption policy as its parent directory.

2020-12-02fscrypt: introduce fscrypt_prepare_readdir()Eric Biggers
The last remaining use of fscrypt_get_encryption_info() from filesystems is for readdir (->iterate_shared()). Every other call is now in fs/crypto/ as part of some other higher-level operation. We need to add a new argument to fscrypt_get_encryption_info() to indicate whether the encryption policy is allowed to be unrecognized or not. Doing this is easier if we can work with high-level operations rather than direct filesystem use of fscrypt_get_encryption_info(). So add a function fscrypt_prepare_readdir() which wraps the call to fscrypt_get_encryption_info() for the readdir use case.

2020-12-02ext4: don't call fscrypt_get_encryption_info() from dx_show_leaf()Eric Biggers
The call to fscrypt_get_encryption_info() in dx_show_leaf() is too low in the call tree; fscrypt_get_encryption_info() should have already been called when starting the directory operation. And indeed, it already is. Moreover, the encryption key is guaranteed to already be available because dx_show_leaf() is only called when adding a new directory entry. And even if the key wasn't available, dx_show_leaf() uses fscrypt_fname_disk_to_usr() which knows how to create a no-key name. So for the above reasons, and because it would be desirable to stop exporting fscrypt_get_encryption_info() directly to filesystems, remove the call to fscrypt_get_encryption_info() from dx_show_leaf().

2020-12-02ubifs: remove ubifs_dir_open()Eric Biggers
Since encrypted directories can be opened and searched without their key being available, and each readdir and ->lookup() tries to set up the key, trying to set up the key in ->open() too isn't really useful. Just remove it so that directories don't need an ->open() method anymore, and so that we eliminate a use of fscrypt_get_encryption_info() (which I'd like to stop exporting to filesystems).
