+Subject: [PATCH] ideapad-laptop: Add Lenovo Yoga 900 to no_hw_rfkill dmi list
+
+Like some of the other Yoga models the Lenovo Yoga 900 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 900 to the no_hw_rfkill dmi list, fixing
+the wifi breakage.
