From cc22d2206d83d6ab76172eeadb34f6b825c1ed9a Mon Sep 17 00:00:00 2001 From: David Plowman Date: Thu, 25 Feb 2021 17:01:41 +0000 Subject: ipa: raspberrypi: AWB: Ignore invalid statistics zones correctly Regions of the image where the statistics are not trusted should not be put in the zones_ list. This also means that the AWB may fail to run initially, so async_results_ needs to be initialised to some kind of default. Finally, the RGB zone structures can be zero-initialised safely now, the previous value of -1 would seem unusual.
