Subject: [PATCH] drm/exynos: trigger build of all modules
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Add COMPILE_TEST dependency to force exynos driver to
built for more than arm and to built modules
that otherwise required other symbols to be de-selected.

This will increase build coverage of the exynos driver
thus allowing most trivial build errors to be detected/fixed early.

This introduces one warning when built using sh:
exynos7_drm_decon.c: In function ‘decon_remove’:
exynos7_drm_decon.c:769:24: warning: unused variable ‘ctx’
  struct decon_context *ctx = dev_get_drvdata(&pdev->dev);

This is due to the definition of iounmap() in sh,
and nothing that exynos driver can fix.

Include fix of exynos build for alpha.
