Subject: ipq806x: fix Zyxel NBG6817 WiFi button
X-Git-Url: http://git.ozo.com/?p=lede-git%2F.git;a=commitdiff_plain;h=f4d4a3c0ef5839e3a8e15027870520fe0b48312c

ipq806x: fix Zyxel NBG6817 WiFi button

Zyxel NBG6817 features a WiFi button, which becomes functional by setting
correct GPIO. It is a switch-type button, so it emits KEY_RFKILL on each ON
and OFF state. This is achieved by setting input-type to EV_SW.
