[PATCH 1/10] KVM: PPC: Book3S HV: Use ARRAY_SIZE macro

From: Thomas Meyer
Date: Sun Sep 03 2017 - 08:33:56 EST


Use ARRAY_SIZE macro, rather than explicitly coding some variant of it
yourself.
Found with: find -type f -name "*.c" -o -name "*.h" | xargs perl -p -i -e
's/\bsizeof\s*\(\s*(\w+)\s*\)\s*\ /\s*sizeof\s*\(\s*\1\s*\[\s*0\s*\]\s*\)
/ARRAY_SIZE(\1)/g' and manual check/verification.
