From 1d2dc5b7b32393bb2d818e0de82a66b1a654d329 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Fri, 19 Dec 2014 13:40:19 +0200 Subject: [PATCH] Bluetooth: Split hci_update_page_scan into two functions To keep the parameter list and its semantics clear it makes sense to split the hci_update_page_scan function into two separate functions: one taking a hci_dev and another taking a hci_request. The one taking a hci_dev constructs its own hci_request and then calls the other function.
