From f4fe8cf58820c171d6d355001ff4bdf17484275a Mon Sep 17 00:00:00 2001 From: Dafna Hirschfeld Date: Tue, 9 Mar 2021 07:38:28 +0100 Subject: ipa: rkisp1: Return error from IPA's configure method if it fails The IPA of rkisp1 relies on some of the camera's controls. Therefore it can't work if those controls are not given. Return -EINVAL from 'configure' in that case. Also return error from the pipeline's 'configure' method if the IPA configure fails.
