2013-03-15usb: misc: sisusbvga: Avoid NULL pointer dereference from sisusbColin Ian King1-1/+1
A failed kzalloc() is reported with a dev_err that dereferences the null sisusb, this will cause a NULL pointer deference error. Instead, pass dev->dev to the dev_err() rather than &sisusb->sisusb_dev->dev Smatch analysis: drivers/usb/misc/sisusbvga/sisusb.c:3087 sisusb_probe() error: potential null dereference 'sisusb'.

2013-01-31USB: altsetting overrides for usbtestAlan Stern1-1/+12
The usbtest driver includes some rather simple-minded logic for selecting an altsetting to test. It doesn't work well for the g_zero gadget, because it selects altsetting 0 (which doesn't have isochronous endpoints) rather than altsetting 1 (which does have them, if the gadget's hardware supports them). This prevents usbtest's isochronous tests (15, 16, 22, and 23) from working with g_zero. Since g_zero is one of the most common gadget drivers used for USB testing, usbtest should do a better job of supporting it. But since some programs may rely on the current scheme for selecting altsettings, I didn't want to change it. Instead, this patch (as1655) adds a module parameter to usbtest, which can be used to override the default altsetting. Since usbtest is never used by normal users (most distributions probably don't even build it), the new module parameter won't inconvenience anybody. In any case, it is entirely optional -- leaving it unset preserves the existing behavior. The patch also fixes a related bug in usbtest: After selecting an altsetting, the driver neglects to store its selection.
