Subject: platform/x86: dell-laptop: Add quirk entry for Latitude 7520
X-Git-Tag: v6.6.17~7515^2~44
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=24ba808a1fffdb136f5e9d418cf1fbe684041fa4;p=platform%2Fkernel%2Flinux-rpi.git

platform/x86: dell-laptop: Add quirk entry for Latitude 7520

The Latitude 7520 supports AC timeouts, but it has no KBD_LED_AC_TOKEN
and so changes to stop_timeout appear to have no effect if the laptop
is plugged in.
