From 630217db71de5d13772eefeb2e90f95cb5f1de9e Mon Sep 17 00:00:00 2001 From: Stanley Chu Date: Fri, 29 Aug 2025 09:23:09 +0800 Subject: [PATCH] i3c: master: svc: Recycle unused IBI slot [ Upstream commit 3448a934ba6f803911ac084d05a2ffce507ea6c6 ] In svc_i3c_master_handle_ibi(), an IBI slot is fetched from the pool to store the IBI payload. However, when an error condition is encountered, the function returns without recycling the IBI slot, resulting in an IBI slot leak.
