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

From: Mario Limonciello <mario_limonciello@...l.com>

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.
