Subject: [PATCH 1/1] tty: serial: pch_uart: use dmaengine_submit() instead of ->tx_submit()
Date: Fri, 2 Oct 2026 16:09:23 -0400 [thread overview]
Message-ID: <20261002200927.236033-1-Frank.Li@oss.nxp.com> (raw)
From: Frank Li <Frank.Li@nxp.com>
Replace direct dma_async_tx_descriptor->tx_submit() calls with the
proper dmaengine_submit() API wrapper.
