[PATCH] arch/powerpc: Remove unnecessary endian conversion code in XICS

From: Gautam Menghani
Date: Fri Jun 30 2023 - 01:56:58 EST


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.
