Subject: [PATCH 1/9] drm/exynos: remove exynos_drm_fb_set_buf_cnt()
Date: Tue, 01 Sep 2015 16:22:47 +0900	[thread overview]
Message-ID: <1441092175-18187-1-git-send-email-jy0922.shim@samsung.com> (raw)

The exynos_drm_fb_set_buf_cnt() is used to set buffer count only in
exynos_drm_fbdev_update(). This patch sets directly buffer count in
exynos_drm_framebuffer_init() without using exynos_drm_fb_set_buf_cnt(),
so there is no any reason to keep exynos_drm_fb_set_buf_cnt().
