Subject: [PATCH v2 1/2] drm/selftests/mm: Switch to bitmap_zalloc()
Date: Mon,  4 Mar 2019 11:29:07 +0200	[thread overview]
Message-ID: <20190304092908.57382-1-andriy.shevchenko@linux.intel.com> (raw)

Switch to bitmap_zalloc() to show clearly what we are allocating.
Besides that it returns pointer of bitmap type instead of opaque void *.
