[PATCH] dell-laptop: rfkill blacklist Dell XPS 13z, 15z

From: Kamal Mostafa
Date: Mon May 14 2012 - 15:27:42 EST


From: Mario Limonciello <mario_limonciello@xxxxxxxx>

On Dell XPS 13z (L321X) and 15z (L502X), switching off Bluetooth also
disables wifi due to improper improper BIOS interaction with dell-laptop.
Add those models to the rfkill blacklist.
