Subject: [PATCH] drm/exynos: constify exynos_drm_crtc_ops structures
Date: Mon, 9 Jan 2017 23:24:53 +0530 [thread overview]
Message-ID: <1483984493-25284-1-git-send-email-bhumirks@gmail.com> (raw)
Declare exynos_drm_crtc_ops structures as const as they are only passed
as an argument to the function exynos_drm_crtc_create. This argument is
of type const struct exynos_drm_crtc_ops *, so exynos_drm_crtc_ops
structures having this property can be declared const.
Done using Coccinelle:
