From 2101af47e4ea9f6a949be75ee8595ab9de38c59a Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 21 Jul 2022 13:13:04 +0100 Subject: ipa: libipa: Pass a reference instead of pointer to Algorithm::process() Frame contexts will become the core component of IPA modules, always available to functions of the algorithms. To indicate and prepare for this, turn the frame context pointer passed to Algorithm::process() into a reference. The RkISP1 IPA module doesn't use frame contexts yet, so pass a dummy context for now. While at it, drop an unneeded [[maybe_unused]] from Agc::process() and add a missing parameter documentation for the frameContext argument to Awb::process().
