From 6e514e371757a62996881e94dd2a488b3e16d518 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 4 Mar 2019 11:29:08 +0200 Subject: [PATCH] drm/i915: 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 *.
