* USB: drivers/usb/misc: Use an IS_ERR test rather than a NULL testJulien Brunel2008-10-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | In case of error, the function backlight_device_register returns an ERR pointer, but never returns a NULL pointer. So a NULL test that may come after a call to this function should be strengthened by an IS_ERR test. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @match_bad_null_test@ expression x, E; statement S1,S2; @@ x = backlight_device_register(...) ... when != x = E * if (x != NULL) S1 else S2 // </smpl> Signed-off-by: Julien Brunel <brunel@diku.dk> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* usb: auerswald: remove driver (obsolete)Wolfgang Mües2008-08-133-2163/+0
| | | | | | | | | | | | | | | | | | | | | | | This patch removes the auerswald USB driver from the linux kernel 2.6.26. This driver was included into the kernel mainly to connect to the ISDN framework. This was done in linux 2.4.x. For 2.6.x, due to the fragile and moving ISDN support, this connection was never realized, and the only use of this driver was for device configuration. In the age of DSL, the demand of ISDN support is getting very low. Meanwhile, with the advent of libusb, an userspace driver was done for the device configuration which works fine for linux and mac. (Thanks to the libusb developers!). The userspace driver is downloadable from the auerswald web site. So this driver is obsolete now and has to be removed. Many thanks to all developers which helped me to bring this driver up and working. Signed-off-by: Wolfgang Muees <wolfgang@iksw-muees.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* Rename WARN() to WARNING() to clear the namespaceArjan van de Ven2008-07-251-2/+2
| | | | | | | | | | | | | We want to use WARN() as a variant of WARN_ON(), however a few drivers are using WARN() internally. This patch renames these to WARNING() to avoid the namespace clash.

* USB: Firmware loader driver for USB Apple iSight cameraMatthew Garrett2008-05-293-0/+143
| | | | | | | | | | | | | | | | | Uninitialised Apple iSight drivers present with a distinctive USB ID. Once firmware has been uploaded, they disconnect and reconnect with a new ID. At this point they can be driven by the uvcvideo driver. As this is unique to the Apple cameras and not functionality shared by any other UVC devices, it makes sense to provide the firmware loading functionality in a separate driver. This driver will read an isight.fw file extracted from the Apple driver using the tools at http://bersace03.free.fr/ift/ and upload it to the camera. It will also handle the case where the device loses its firmware during hibernation and must have it reloaded.

* USB: Phidget: fix race in device_createGreg Kroah-Hartman2008-05-203-10/+9
| | | | | | | | | | | | | | | | There is a race from when a device is created with device_create() and then the drvdata is set with a call to dev_set_drvdata() in which a sysfs file could be open, yet the drvdata will be NULL, causing all sorts of bad things to happen. This patch fixes the problem by using the new function, device_create_drvdata(). It fixes all 3 phidget drivers, which all have the same problem.

* USB: remove PICDEM FS USB demo (04d8:000c) device from ldusbXiaofan Chen2008-05-141-4/+0
| | | | | | | | | | | | | | | | | Microchip has changed the PICDEM FS USB demo device (0x04d8:000c) to use bulk transfer and not interrupt transfer. So I've updated the libusb based program here (Post #31). http://forum.microchip.com/tm.aspx?m=106426&mpage=2 So I believe that the in-kernel ldusb driver will no longer work with the demo firmware.

* USB: usbtest displays diagnostics againDavid Brownell2008-05-021-143/+133
| | | | | | | | | | | | | | | | | | | | | | | Minor cleanup to the "usbtest" driver, mostly to resolve a regression: all the important diagnostics were at KERN_DEBUG, so that when the "#define DEBUG" was removed from the top of that file it stopped providing diagnostics. Fix by using KERN_ERROR. Also: - Stop using the legacy dbg() calls - Simplify the internal debug macros - Correct some test descriptions: * Test #10 subcase 7 should *always* stall * Test #10 subcase 8 *may* stall - Diagnostic about control queue test failures is more informative - Fix some whitespace "bugs" And add a warning about the rude interaction between usbfs ioctl() and khubd during device disconnect ... don't unplug a device under test, that will wedge.
