Subject: powerpc/pseries/hotplug-memory.c: Replace nested ifs by switch-case
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9616dda1aaddb2080122aaeab96ad7fc064e36b4;p=openwrt%2Fstaging%2Fblogic.git

powerpc/pseries/hotplug-memory.c: Replace nested ifs by switch-case

I noticed these nested ifs can be easily replaced by switch-cases,
which can improve readability.
