From 02bc2a8a24baaff82d1c5f8cb5d9ab7d1afab426 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sat, 22 Oct 2022 01:21:05 +0300 Subject: ipa: Sort algorithm operations based on calling order Reorder functions in the base ipa::Algorithm and its derived classes to match the calling order: queueRequest(), prepare() and process(). This makes the code flow easier to read. No functional change intended.
