Subject: [PATCH 4.2.y-ckt 191/268] ideapad-laptop: Add Lenovo Yoga 700 to no_hw_rfkill dmi list

4.2.8-ckt3 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Josh Boyer <jwboyer@...oraproject.org>

commit 6b31de3e698582fe0b8f7f4bab15831b73204800 upstream.

Like the Yoga 900 models the Lenovo Yoga 700 does not have a
hw rfkill switch, and trying to read the hw rfkill switch through the
ideapad module causes it to always reported blocking breaking wifi.

This commit adds the Lenovo Yoga 700 to the no_hw_rfkill dmi list, fixing
the wifi breakage.
