* move asm/unaligned.h to linux/unaligned.hAl Viro2024-10-021-1/+1
| | | | | | | | | | | | | | | | | | | asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h
* usb: atm: cxacru: fix endpoint checking in cxacru_bind()Nikita Zhandarovich2024-06-201-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Syzbot is still reporting quite an old issue [1] that occurs due to incomplete checking of present usb endpoints. As such, wrong endpoints types may be used at urb sumbitting stage which in turn triggers a warning in usb_submit_urb(). Fix the issue by verifying that required endpoint types are present for both in and out endpoints, taking into account cmd endpoint type. Unfortunately, this patch has not been tested on real hardware.

* USB: atm: Remove redundant license textGreg Kroah-Hartman2017-11-041-15/+0
| | | | | | | | | | | | | | | | Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

* USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman2017-11-041-0/+1

Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The command endpoint is either a bulk or interrupt endpoint, but using the wrong type of transfer causes an error if CONFIG_USB_DEBUG is enabled after commit f661c6f8c67bd55e93348f160d590ff9edf08904, which checks for this mismatch. Detect which type of endpoint it is and use a bulk/int URB as appropriate.

* USB: cxacru: Use appropriate logging for errorsSimon Arlott2007-10-121-15/+28
| | | | | | | | | | | | | | | | When an error occurs, existing logging uses dbg() so the cause of a problem is hard to determine. Error conditions shouldn't only be properly reported with debugging enabled. A side effect of this change is that when an uninitialised device is started, a log message similar to the following is sent: cxacru 5-2:1.0: receive of cm 0x90 failed (-104) This is normal - the device did not respond so firmware will be loaded.

* USB: unkill cxacru atm driverOliver Neukum2007-08-221-2/+1
| | | | | | | | | | | it seems like you overdid it a bit in your quest to clean up the use of urb->status. In this driver you read it the first thing, which means that you are in a race against URB completion you'll usually lose, returning -EINPROGRESS. This kills the driver.

* USB: cxacru: Cleanup sysfs attribute codeSimon Arlott2007-07-131-42/+31
| | | | | | | | | | | | | This changes the format of unknown status values to be less verbose and uses an array instead of several different snprintf calls. Since only enum values are assigned to it, poll_state is changed from int to enum. Use abs() for dB values instead of two almost identical return lines.
