From 3d381442253fba4887b214565d0de0d3d93023bf Mon Sep 17 00:00:00 2001 From: Stanley Chu Date: Tue, 18 Mar 2025 13:36:04 +0800 Subject: [PATCH] i3c: master: svc: Fix missing the IBI rules [ Upstream commit 9cecad134d84d14dc72a0eea7a107691c3e5a837 ] The code does not add IBI rules for devices with controller capability. However, the secondary controller has the controller capability and works at target mode when the device is probed. Therefore, add IBI rules for such devices.
