From d231fb443d8d4042f0dd705b93beba8c916a7344 Mon Sep 17 00:00:00 2001 From: Stanley Chu Date: Tue, 18 Mar 2025 13:36:06 +0800 Subject: [PATCH] i3c: master: svc: Fix missing STOP for master request [ Upstream commit 0430bf9bc1ac068c8b8c540eb93e5751872efc51 ] The controller driver nacked the master request but didn't emit a STOP to end the transaction. The driver shall refuse the unsupported requests and return the controller state to IDLE by emitting a STOP.
