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 36735783fdb599c94b9c86824583df367c65900b Mon Sep 17 00:00:00 2001 From: Hiromitsu Yamasaki Date: Thu, 2 Nov 2017 10:32:36 +0100 Subject: [PATCH] spi: sh-msiof: Fix DMA transfer size check DMA supports 32-bit words only, even if BITLEN1 of SITMDR2 register is 16bit.
