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.
