usb: uvc: Enumerate valid values for color matching

2023-03-11T15:44:15Z

[ Upstream commit e16cab9c1596e251761d2bfb5e1467950d616963 ] The color matching descriptors defined in the UVC Specification contain 3 fields with discrete numeric values representing particular settings. Enumerate those values so that later code setting them can be more readable.

usb: webcam: Invalid size of Processing Unit Descriptor

2021-05-11T12:04:05Z

[ Upstream commit 6a154ec9ef6762c774cd2b50215c7a8f0f08a862 ] According with USB Device Class Definition for Video Device the Processing Unit Descriptor bLength should be 12 (10 + bmControlSize), but it has 11. Invalid length caused that Processing Unit Descriptor Test Video form CV tool failed. To fix this issue patch adds bmVideoStandards into uvc_processing_unit_descriptor structure. The bmVideoStandards field was added in UVC 1.1 and it wasn't part of UVC 1.0a.

treewide: add "WITH Linux-syscall-note" to SPDX tag of uapi headers

2019-07-25T09:05:10Z

UAPI headers licensed under GPL are supposed to have exception "WITH Linux-syscall-note" so that they can be included into non-GPL user space application code. The exception note is missing in some UAPI headers. Some of them slipped in by the treewide conversion commit b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license"). Just run: $ git show --oneline b24413180f56 -- arch/x86/include/uapi/asm/ I believe they are not intentional, and should be fixed too. This patch was generated by the following script: git grep -l --not -e Linux-syscall-note --and -e SPDX-License-Identifier \ -- :arch/*/include/uapi/asm/*.h :include/uapi/ :^*/Kbuild | while read file do sed -i -e '/[[:space:]]OR[[:space:]]/s/$GPL-[^[:space:]]*$/(\1 WITH Linux-syscall-note)/g' \ -e '/[[:space:]]or[[:space:]]/s/$GPL-[^[:space:]]*$/(\1 WITH Linux-syscall-note)/g' \ -e '/[[:space:]]OR[[:space:]]/!{/[[:space:]]or[[:space:]]/!s/$GPL-[^[:space:]]*$/\1 WITH Linux-syscall-note/g}' $file done After this patch is applied, there are 5 UAPI headers that do not contain "WITH Linux-syscall-note". They are kept untouched since this exception applies only to GPL variants. $ git grep --not -e Linux-syscall-note --and -e SPDX-License-Identifier \ -- :arch/*/include/uapi/asm/*.h :include/uapi/ :^*/Kbuild include/uapi/drm/panfrost_drm.h:/* SPDX-License-Identifier: MIT */ include/uapi/linux/batman_adv.h:/* SPDX-License-Identifier: MIT */ include/uapi/linux/qemu_fw_cfg.h:/* SPDX-License-Identifier: BSD-3-Clause */ include/uapi/linux/vbox_err.h:/* SPDX-License-Identifier: MIT */ include/uapi/linux/virtio_iommu.h:/* SPDX-License-Identifier: BSD-3-Clause */ Signed-off-by: Masahiro Yamada Reviewed-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

ALSA: usb-audio: Fix parse of UAC2 Extension Units

2019-07-05T06:06:47Z

Extension Unit (XU) is used to have a compatible layout with Processing Unit (PU) on UAC1, and the usb-audio driver code assumed it for parsing the descriptors. Meanwhile, on UAC2, XU became slightly incompatible with PU; namely, XU has a one-byte bmControls bitmap while PU has two bytes bmControls bitmap. This incompatibility results in the read of a wrong address for the last iExtension field, which ended up with an incorrect string for the mixer element name, as recently reported for Focusrite Scarlett 18i20 device. This patch corrects this misalignment by introducing a couple of new macros and calling them depending on the descriptor type.

usb: usbtmc: Add ioctl USBTMC_IOCTL_API_VERSION

2018-09-20T11:04:02Z

Add ioctl USBTMC_IOCTL_API_VERSION to get current API version of usbtmc driver. This is to allow an instrument library to determine whether the driver API is compatible with the implementation. The API may change in future versions. Therefore the macro USBTMC_API_VERSION should be incremented when changing tmc.h with new flags, ioctls or when changing a significant behavior of the driver.
