From 92e830f25fc0be447486a4658887ded68ef824f5 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 4 Apr 2018 14:44:54 +0200 Subject: [PATCH] x86/olpc: Fix inconsistent MFD_CS5535 configuration This Kconfig warning appeared after a fix to the Kconfig validation. The GPIO_CS5535 driver depends on the MFD_CS5535 driver, but the former is selected in places where the latter is not: WARNING: unmet direct dependencies detected for GPIO_CS5535 Depends on [m]: GPIOLIB [=y] && (X86 [=y] || MIPS || COMPILE_TEST [=y]) && MFD_CS5535 [=m] Selected by [y]: - OLPC_XO1_SCI [=y] && X86_32 [=y] && OLPC [=y] && OLPC_XO1_PM [=y] && INPUT [=y]=y The warning does seem appropriate, since the GPIO_CS5535 driver won't work unless MFD_CS5535 is also present. However, there is no link time dependency between the two, so this caused no problems during randconfig testing before. This changes the 'select GPIO_CS5535' to 'depends on GPIO_CS5535' to avoid the issue, at the expense of making it harder to configure the driver (one now has to select the dependencies first). The 'select MFD_CORE' part is completely redundant, since we already depend on MFD_CS5535 here, so I'm removing that as well. Ideally, the private symbols exported by that cs5535 gpio driver would just be converted to gpiolib interfaces so we could expletely avoid this dependency.
