[Bionic][PATCH 03/18] powerpc: Use sizeof(*foo) rather than sizeof(struct foo)
Jose Ricardo Ziviani
joserz at linux.ibm.com
Wed Oct 31 15:09:16 UTC 2018
From: Markus Elfring <elfring at users.sourceforge.net>
BugLink: https://bugs.launchpad.net/qemu-kvm/+bug/1800649
It's slightly less error prone to use sizeof(*foo) rather than
specifying the type.
