Subject: [PATCH 02/14] drm/exynos: remove function convert_to_vm_err_msg
Date: Tue, 28 Jul 2015 17:53:17 +0900	[thread overview]
Message-ID: <1438073609-32664-2-git-send-email-jy0922.shim@samsung.com> (raw)
In-Reply-To: <1438073609-32664-1-git-send-email-jy0922.shim@samsung.com>

The convert_to_vm_err_msg is called just once by exynos_drm_gem_fault,
so it's simple not to use the function.
