You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From 401abb764abb6e42f539528e02127457eb0c5b32 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Thu, 12 Dec 2019 15:55:47 +0200 Subject: [PATCH] spi: sirf: Use dma_request_chan() instead dma_request_slave_channel() dma_request_slave_channel() is a wrapper on top of dma_request_chan() eating up the error code. By using dma_request_chan() directly the driver can support deferred probing against DMA.
