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 7e2ef003302cc797917ce0a2a32cffb4af42c99e Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Wed, 30 Nov 2016 20:28:09 +0100 Subject: [PATCH] spi: fsl-espi: fix ioread16/iowrite16 endianness fsl_espi_read_reg16 / fsl_espi_write_reg16 are supposed to read / write big endian values. Therefore ioread16be / iowrite16be have to be used.
