As other people have said:

This function is usb_device_reset(). If that function name string is to be
used in the message, it should be done so by using __func__.
See http://marc.info/?l=linux-driver-devel&m=149095639202492&w=2

Or is the called (failing) function name is to be kept in the message (as it
is currently), then the message should contain "usb_reset_device" instead of
"usb_device_reset". See http://marc.info/?l=linux-driver-devel&m=149098680312723&w=2
