[ Upstream commit fa112cf1e8bc693d5a666b1c479a2859c8b6e0f1 ]
When building a 32-bit config which has the above MFD item as module but OLPC_XO1_PM is enabled =y - which is bool, btw - the kernel fails building with:
ld: arch/x86/platform/olpc/olpc-xo1-pm.o: in function `xo1_pm_remove': /home/boris/kernel/linux/arch/x86/platform/olpc/olpc-xo1-pm.c:159: undefined reference to `mfd_cell_disable' ld: arch/x86/platform/olpc/olpc-xo1-pm.o: in function `xo1_pm_probe': /home/boris/kernel/linux/arch/x86/platform/olpc/olpc-xo1-pm.c:133: undefined reference to `mfd_cell_enable' make: *** [Makefile:1030: vmlinux] Error 1
Force MFD_CS5535 to y if OLPC_XO1_PM is enabled.
