Revision 67f5a4ba9741fcef3f4db3509ad03565d9e33af2 authored by Alan Stern on 20 February 2009, 21:33:08 UTC, committed by Greg Kroah-Hartman on 27 February 2009, 22:40:50 UTC
This patch (as1218) fixes a problem with a radio-control joystick used
in the "walkera 4#3" helicopter.  This device responds to the initial
Get-String-Descriptor request for string 0 (which is really the list
of supported languages) by sending its config descriptor!  The
usb_get_string() routine needs to check whether it got the right
type of descriptor.

Oddly enough, this sort of check is already present in
usb_get_descriptor().  The patch changes the error code from -EPROTO
to -ENODATA, because -EPROTO shows up in so many other contexts to
indicate a hardware failure rather than a firmware error.
