Subject: [PATCH 4/5] drm/client: Remove unused drm_client_framebuffer_flush

From: "Dr. David Alan Gilbert" <linux@...blig.org>

drm_client_framebuffer_flush() was explicitly added in 2020
by
commit c9c03e3cf072 ("drm/client: Add drm_client_framebuffer_flush()")
but has never been used.

Remove it.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
