Subject: [PATCH] Bluetooth: hci_nokia: Save a few cycles in 'nokia_enqueue()'
Git-commit: 088fc633f2d99fee8cbe82047e01068e1c5ffab6
Patch-mainline: v5.5-rc1
References: jsc#SLE-13430
'skb_pad()' a few lines above already initializes the "padded" byte to 0.
So there is no need to do it twice.
All what is needed is to increase the len of the skb. So 'skb_put(..., 1)'
is enough here.
