From 9230cf69cb0907548eb8cc7460547db053615192 Mon Sep 17 00:00:00 2001 From: Umang Jain Date: Thu, 31 Mar 2022 20:24:44 +0530 Subject: ipa: ipu3: Inline fillParams() in fillParamsBuffer() Since we have moved away from switch/case on the operation ID, there's little reason to split the operation in two functions.
