From 3f1808f63f0458762403549b3d975ef6e971b6e0 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 18 Jun 2021 18:16:52 +0300 Subject: [PATCH] irqchip/alpine-msi: Switch to bitmap_zalloc() Switch to bitmap_zalloc() to show clearly what we are allocating. Besides that it returns pointer of bitmap type instead of opaque void *.
