Subject: libusb-1.0.22 deprecated libusb_set_debug() with libusb_set_option()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This avoids the following compiler warnings when using more recent
versions of libusb:

src/libosmo-fl2k.c:384:2: warning: ‘libusb_set_debug’ is deprecated: Use libusb_set_option instead [-Wdeprecated-declarations]
  libusb_set_debug(dev->ctx, 3);
  ^~~~~~~~~~~~~~~~
