Subject: [PATCH v1 1/4] dmaengine: Replace dma_request_slave_channel() by dma_request_chan()
Date: Mon,  7 Oct 2024 18:06:45 +0300	[thread overview]
Message-ID: <20241007150852.2183722-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20241007150852.2183722-1-andriy.shevchenko@linux.intel.com>

Replace dma_request_slave_channel() by dma_request_chan() as suggested
since the former is deprecated.
