Subject: [PATCH 0/4] drm/simple_kms_helper: Add {enable|disable}_vblank callback support

From: Oleksandr Andrushchenko <oleksandr_andrushchenko@...m.com>

If simple_kms_helper based driver needs to work with vblanks,
then it has to provide drm_driver.{enable|disable}_vblank callbacks,
because drm_simple_kms_helper.drm_crtc_funcs does not provide any.
At the same time drm_driver.{enable|disable}_vblank callbacks
are marked as deprecated and shouldn't be used by new drivers.

Fix this by extending drm_simple_kms_helper.drm_crtc_funcs
to provide the missing callbacks.

Please note, that patch for the DRM core (drm_simple_kms_helper.*)
is checked at run-time (I use this patch for my own driver), but patches
0002-0004 are compile only checked.

Thank you,
Oleksandr Andrushchenko
