From 2fe4ca6ad7f6a0b98f97c498320051e5066e4b95 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Fri, 17 Dec 2021 22:54:12 +0100 Subject: powerpc/mpic: Use bitmap_zalloc() when applicable 'mpic->protected' is a bitmap. So use 'bitmap_zalloc()' to simplify code and improve the semantic, instead of hand writing it.
