Subject: Bluetooth: Track current configured LE scan type parameter
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=533553f8738184bcf957d97fed9eb4d5f023e4a7;p=linux-beck.git

Bluetooth: Track current configured LE scan type parameter

The LE scan type paramter defines if active scanning or passive scanning
is in use. Track the currently set value so it can be used for decision
making from other pieces in the core.
