Subject: ipa: raspberry: awb: Include <functional>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Building on gcc8 on Debian 10 fails with

 asyncThread_ = std::thread(std::bind(&Awb::asyncFunc, this));
../src/ipa/raspberrypi/controller/rpi/awb.cpp:177:34: note: ‘std::bind’
is defined in header ‘<functional>’; did you forget to ‘#include
<functional>’?

Fix that by including <functional> in awb.cpp.
