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 757ec116c9bce4278fa4423039736c832cc63b6f Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 14 Nov 2018 21:42:46 +0000 Subject: [PATCH] spi: npcm: fix u32 csgpio being checked for less than zero The u32 variable csgpio is being checked for an error return from the call to of_get_named_gpio, however, since this is unsigned this comparison will always be false. Fix this by making csgpio an int and fix up the %u format specifiers to %d accordingly.
