Subject: [PATCH v3 1/4] amdgpu/dc/dml: Consolidate redundant CFLAGS
Date:   Thu,  8 Feb 2018 12:53:13 -0800
Message-Id: <20180208205316.93330-1-mka@chromium.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use a variable for common CFLAGS instead of specifying the same flags
for every source file.

Signed-off-by: Matthias Kaehlcke <mka@chromium.org>

Changes in v3:
- Use variable for compiler options instead of subdir-ccflags-y
