Subject: [PATCH 3.10 71/86] net: qmi_wwan: fixup Sierra Wireless MC8305 entry

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: =?UTF-8?q?Bj=C3=B8rn=20Mork?= <bjorn@...k.no>

[ Upstream commit 5a008ffa73b4401251d548c10cadac6f8a67cfb5 ]

The MC8305 module got an additional entry added based solely on
information from a Windows driver *.inf file. We now have the
actual descriptor layout from one of these modules, and it
consists of two alternate configurations where cfg #1 is a
normal Gobi 2k layout and cfg #2 is MBIM only, using interface
numbers 5 and 6 for MBIM control and data. The extra Windows
driver entry for interface number 5 was most likely a bug.

Deleting the bogus entry to avoid unnecessary qmi_wwan probe
failures when using the MBIM configuration.
