usb: core: use sysfs_emit() instead of sprintf()

2024-10-29T03:33:49+00:00

Follow the advice in Documentation/filesystems/sysfs.rst: show() should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space.

usb: core: constify the struct device_type usage

2024-02-19T08:35:46+00:00

Since commit aed65af1cc2f ("drivers: make device_type const"), the driver core can properly handle constant struct device_type. Move the usb_device_type, usb_if_device_type, usb_ep_device_type and usb_port_device_type variables to be constant structures as well, placing it into read-only memory which can not be modified at runtime.

usb: common: add function to get interval expressed in us unit

Add a new function to convert bInterval into the time expressed in 1us unit. Signed-off-by: Chunfeng Yun Link: https://lore.kernel.org/r/25c8a09b055f716c1e5bf11fea72c3418f844482.1615170625.git.chunfeng.yun@mediatek.com Signed-off-by: Greg Kroah-Hartman

USB: core: Constify static attribute_group structs

2020-11-26T12:40:42+00:00

These are never modified, so make them const to allow the compiler to put them in read-only memory. Done with the help of coccinelle. Signed-off-by: Rikard Falkeborn Link: https://lore.kernel.org/r/20201125162500.37228-2-rikard.falkeborn@gmail.com Signed-off-by: Greg Kroah-Hartman

USB: core: move existing SPDX tags to top of the file

2017-11-03T09:12:26+00:00

To match the rest of the kernel, the SPDX tags for the drivers/usb/core/ files are moved to the first line of the file. This makes it more obvious the tag is present as well as making it match the other 12k files in the tree with this location. It also uses // to match the "expected style" as well.

Merge tag 'usb-for-v4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

2016-11-18T15:02:15+00:00

Felipe writes: usb: patches for v4.10 merge window One big merge this time with a total of 166 non-merge commits. Most of the work, by far, is on dwc2 this time (68.2%) with dwc3 a far second (22.5%). The remaining 9.3% are scattered on gadget drivers. The most important changes for dwc2 are the peripheral side DMA support implemented by Synopsys folks and support for the new IOT dwc2 compatible core from Synopsys. In dwc3 land we have support for high-bandwidth, high-speed isochronous endpoints and some non-critical fixes for large scatter lists. Apart from these, we have our usual set of cleanups, non-critical fixes, etc.

usb: core: endpoint: remove unnecessary & operation

2016-11-03T08:38:24+00:00

Now that usb_endpoint_maxp() only returns the lowest 11 bits from wMaxPacketSize, we can remove the & operation from this driver. Cc: Greg Kroah-Hartman Acked-by: Greg Kroah-Hartman Signed-off-by: Felipe Balbi

USB: core: add missing license information to some files

2016-10-29T16:51:56+00:00

Some of the USB core files were missing explicit license information. As all files in the kernel tree are implicitly licensed under the GPLv2-only, be explicit in case someone get confused looking at individual files by using the SPDX nomenclature. Signed-off-by: Greg Kroah-Hartman

USB: core: be specific about attribute permissions

2013-08-25T22:12:03+00:00

Instead of having to audit all sysfs attributes, to ensure we get them right, use the default macros the driver core provides us (read-only, read-write) to make the code simpler, and to prevent any mistakes from ever happening. Signed-off-by: Greg Kroah-Hartman
