Subject: RealView: Toggle one LED per CPU
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=da055eb52ec067d51dc08c7e86baf92dd5c01599;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

RealView: Toggle one LED per CPU

If CONFIG_LEDS is enabled, it makes more sense to toggle one LED per CPU
in SMP systems rather than a single LED for all the CPUs.
