The patch spi: fsl-espi: remove unneeded variable in fsl_espi_do_trans has been applied to the spi tree at git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. 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 dbd4fefb5b7cba19e3f89c097d93ad02049e38e3 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit <hkallweit1@xxxxxxxxx> Date: Thu, 25 Aug 2016 06:45:55 +0200 Subject: [PATCH] spi: fsl-espi: remove unneeded variable in fsl_espi_do_trans Creating a message, adding one transfer, and then iterating over all transfers in the message doesn't make sense. We can simply use the original transfer directly.
