2019-03-01wusb: Remove unnecessary static function ckhdid_printfJoe Perches1-11/+4
This static inline is unnecessary and can be removed by using the vsprintf %ph extension. This reduces overall object size by more than 2K.

2017-11-07USB: wusbcore: Remove redundant license textGreg Kroah-Hartman1-15/+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.

2017-11-04USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman1-0/+1
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. 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. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

2013-12-09usb: wusbcore: use USB_CTRL_SET_TIMEOUT and USB_CTRL_GET_TIMEOUTThomas Pugliese1-4/+4
Use USB_CTRL_SET_TIMEOUT and USB_CTRL_GET_TIMEOUT for USB control messages instead of an arbitrary 1s timeout value. This is particularly useful for WUSB since in the worst case RF scanario, a WUSB device can be unresponsive for up to 4s and still be connected.

2013-10-19USB: wusbcore: fix usb_dev leaksAlexey Khoroshilov1-0/+3
cbaf_probe() does cbaf->usb_dev = usb_get_dev(interface_to_usbdev(iface)), but there is no usb_put_dev() anywhere in cbaf. The patch adds usb_put_dev() to cbaf_disconnect() and to an error path in cbaf_probe(). Also it adds missed usb_put_intf(iface) to the error path.

2011-11-18USB: convert drivers/usb/* to use module_usb_driver()Greg Kroah-Hartman1-11/+1
This converts the drivers in drivers/usb/* to use the module_usb_driver() macro which makes the code smaller and a bit simpler. Added bonus is that it removes some unneeded kernel log messages about drivers loading and/or unloading.

2011-06-07USB: wusbcore: return negative error codesDan Carpenter1-2/+2
cbaf_cdid_get() is only used in cbaf_wusb_chid_store(). In the original code cbaf_cdid_get() returns either a negative error code or a small positive value on error. I have changed it to return -ENOENT if there is not enough data available. In the original code the caller changed the negative error codes to positive return values. I've changed it to just return the error value directly. Signed-off-by: Dan Carpenter <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+1
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
