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 faceef390702bad8bdf9c93554a3364253d9d943 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Wed, 7 Sep 2016 22:52:06 +0200 Subject: [PATCH] spi: fsl-espi: eliminate struct fsl_espi_transfer The remaining elements of struct fsl_espi_transfer are part of struct spi_transfer anyway. So we can get rid of struct fsl_espi_transfer and use a struct spi_transfer only.
