Subject: [PATCH libdrm 2/3] amdgpu: vamgr_32 can be a struct instead of a pointer
Date: Sat, 28 Jan 2017 21:49:31 +0200	[thread overview]
Message-ID: <1485632972-4790-3-git-send-email-notasas@gmail.com> (raw)
In-Reply-To: <1485632972-4790-1-git-send-email-notasas-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

From: Alex Xie <AlexBin.Xie@amd.com>

vamgr_32 is an integral part of amdgpu_device. We don't need to calloc and free it.
This can save CPU time, reduce heap fragmentation.
