commit 1ffdb51f28e8ec6be0a2b812c1765b5cf5c44a8f upstream.
This reverts commit a0085f2510e8976614ad8f766b209448b385492f.
This commit has caused regressions in notebooks that support suspend to idle such as the XPS 9360, XPS 9370 and XPS 9380.
These notebooks will wakeup from suspend to idle from an unsolicited advertising packet from an unpaired BLE device.
In a bug report it was sugggested that this is caused by a generic lack of LE privacy support. Revert this commit until that behavior can be avoided by the kernel.
