Subject: [PATCH] arch/powerpc: Remove unnecessary endian conversion code in XICS
Remove an unnecessary piece of code that does an endianness conversion but
does not use the result. The following warning was reported by Clang's
static analyzer:
arch/powerpc/sysdev/xics/ics-opal.c:114:2: warning: Value stored to
'server' is never read [deadcode.DeadStores]
server = be16_to_cpu(oserver);
As the result of endianness conversion is never used, delete the line
and fix the warning.
