From: Paul Fertser Date: Fri, 15 Aug 2014 15:30:47 +0000 (+0400) Subject: jtag/drivers/libusb0_common: fix FTBFS (libusb_device_descriptor error) X-Git-Tag: v0.9.0-rc1~291 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=96549bf0121a7cff08885ddca22ab7a1c362ea24;p=openocd jtag/drivers/libusb0_common: fix FTBFS (libusb_device_descriptor error) This struct and libusb_get_device_descriptor() method are not present in libusb-0.1 API, so when libusb-1.0 is unavailable, this code breaks the build. Fix by using the appropriate struct (which is apparently filled automatically on device initialisation). While at it, change return values for consistency with the callers.
