Subject[PATCH] arm: omap2: remove redundant multiplatform checks
Date
The directory arch/arm/mach-omap2 is only selected for compilation if
CONFIG_ARCH_OMAP2PLUS is selected. CONFIG_ARCH_OMAP2PLUS itself is a
silent option and all machines selecting this option are multiplatform
devices. As a consequence checks for CONFIG_ARCH_MULTIPLATFORM as well
as CONFIG_ARCH_OMAP2PLUS within that directory are superfluous and can
be removed.
