Message-Id: <20250505223922.2682012-85-sashal@kernel.org> Date: Mon, 5 May 2025 18:32:41 -0400 From: Sasha Levin <sashal@...nel.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Stanley Chu <yschu@...oton.com>, Frank Li <Frank.Li@....com>, Alexandre Belloni <alexandre.belloni@...tlin.com>, Sasha Levin <sashal@...nel.org>, miquel.raynal@...tlin.com, linux-i3c@...ts.infradead.org, imx@...ts.linux.dev Subject: [PATCH AUTOSEL 6.12 085/486] i3c: master: svc: Fix missing STOP for master request From: Stanley Chu <yschu@...oton.com> [ 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.
