Subject: [PATCH v7 04/10] drm/exynos: Remove empty exynos_drm_gem_prime_{vmap, vunmap}()
Date: Tue,  3 Nov 2020 10:30:09 +0100
Message-ID: <20201103093015.1063-5-tzimmermann@suse.de> (raw)
In-Reply-To: <20201103093015.1063-1-tzimmermann@suse.de>

The functions exynos_drm_gem_prime_{vmap,vunmap}() are empty. Remove
them before changing the interface to use struct drm_buf_map. As a side
effect of removing drm_gem_prime_vmap(), the error code changes from
ENOMEM to EOPNOTSUPP.

Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de>
