This patchseries replaces drm_handle_vblank() with drm_crtc_handle_vblank(). As a bonus result of this conversion it is possible to drop the stored array of allocated CRTCs and use the core CRTC iterators.
Changes since v3: - In msm_drm_init simplify the code by using an interim var for the event thread itself rather than just the index (suggested by Abhinav)
Changes since v2; - none (sent by mistake)
Changes since v1; - fixed uninitialized var access (LTP Robot)
Dmitry Baryshkov (3): drm/msm/mdp4: convert to drm_crtc_handle_vblank() drm/msm/mdp5: convert to drm_crtc_handle_vblank() drm/msm: stop storing the array of CRTCs in struct msm_drm_private

Stop using deprecated drm_handle_vblank(), use drm_crtc_handle_vblank() instead.

Handling the array of CRTC duplicate the struct msm_drm_private duplicates a list of CRTCs in the drm_device. Drop it and use the existing list for CRTC enumeration.
