2020-07-15USB: sisusbvga: Fix a potential UB casued by left shifting a negative valueChangming Liu
The char buffer buf, receives data directly from user space, so its content might be negative and its elements are left shifted to form an unsigned integer. Since left shifting a negative value is undefined behavior, thus change the char to u8 to elimintate this UB.

2020-07-15USB: Remove pci-dma-compat wrapper APIs.Suraj Upadhyay
The legacy API wrappers in include/linux/pci-dma-compat.h should go away as it creates unnecessary midlayering for include/linux/dma-mapping.h APIs, instead use dma-mapping.h APIs directly. The patch has been generated with the coccinelle script below and compile-tested. @@@@ - 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_consistent_dma_mask(E1, E2) + dma_set_coherent_mask(&E1->dev, E2) @@ expression E1, E2; @@ - pci_set_dma_mask(E1, E2) + dma_set_mask(&E1->dev, E2) Signed-off-by: Suraj Upadhyay <usuraj35@gmail.com> Link: https://lore.kernel.org/r/20200714115249.GA8563@blackclown Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2020-07-14USB: serial: sierra: clean up special-interface handlingJohan Hovold
Clean up the handling of special interfaces that either should be ignored or that need a larger number of URBs. Commit 66f092ed3b94 ("USB: serial: sierra: unify quirk handling logic") replaced the previous is_blacklisted() and is_highmemory() helpers with a single is_quirk() helper which made it even harder to understand what the interface lists were used for. Rename the interface-list struct, its members and the interface-lookup helper and restructure the code somewhat in order to make it more self-explanatory.

Add support for line-status events that specifically can be used to detect and report parity errors. Enable the device's event-insertion mode whenever input-parity checking is requested. This will insert line and modem status events into the data stream. Note that modem-status changes appear to be buffered until a character is received (at least on CP2102) and support is therefore left unimplemented. On at least one type of these chips (CP2102), line breaks are not reported as expected either (regardless of whether SERIAL_BREAK_CHAR is set) so do not enable event-mode when !IGNBRK is requested for now.
