2.6.35-longterm review patch. If anyone has any objections, please let me know.
------------------
From: Jiri Slaby <jsl...@suse.cz>
commit 468c3f924f043cad7a04f4f4d5224a2c9bc886c1 upstream.
Currently, for N 5800 XM I get:
cdc_phonet: probe of 1-6:1.10 failed with error -22
It's because phonet_header is empty. Extra altsetting looks like
there:
E 05 24 00 01 10 03 24 ab 05 24 06 0a 0b 04 24 fd .$....$..$....$.
E 00 .
I don't see the header used anywhere so just check if the phonet
descriptor is there, not the structure itself.
