Subject: [PATCH] ideapad-laptop: Add Lenovo ideapad Y700 Touch-15ISK and
 Lenovo ideapad Y700-15ISK to the no_hw_rfkill DMI list

Some Lenovo ideapad models lack a physical rfkill switch.
On Lenovo models ideapad Y700 Touch-15ISK and ideapad Y700-15ISK,
ideapad-laptop would wrongly report all radios as blocked by
hardware which caused wireless network connections to fail.

Add these models without an rfkill switch to the no_hw_rfkill list.

Relevant kernel versions: 4.5-rc4, 4.4.1, 4.3.5, 4.1.18, 3.18.27
