   4 Subject: [PATCH] Revert "Bluetooth: Always request for user
   5  confirmation for Just Works"
   6
   7 This reverts commit 92516cd97fd4d8ad5b1421a0d51771044f453a5f.
   8
   9 Thi commit "Bluetooth: Always request for user confirmation for Just
  10 Works" prevents BLE devices pairing in (at least) the Raspberry Pi OS
  11 GUI. After reverting it, pairing works again.
  12
  13 If another solution to the problem is found then this reversion will
  14 be removed.
