Merge tag 'for-linus-timers-conversion-final-v4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux into timers/urgent

Pull the last batch of manual timer conversions from Kees Cook:

 - final batch of "non trivial" timer conversions (multi-tree dependencies,
   things Coccinelle couldn't handle, etc).

 - treewide conversions via Coccinelle, in 4 steps:
   - DEFINE_TIMER() functions converted to struct timer_list * argument
   - init_timer() -> setup_timer()
   - setup_timer() -> timer_setup()
   - setup_timer() -> timer_setup() (with a single embedded structure)

 - deprecated timer API removals (init_timer(), setup_*timer())

 - finalization of new API (remove global casts)

- * this func is identical to the drm_atomic_helper_check, but we keep this

- * sequence without using the atomic helpers.
- *
- * In the past, we first called drm_atomic_helper_check_planes, and then
- * drm_atomic_helper_check_modeset. We needed this because the MDP5 plane's
- * ->atomic_check could update ->mode_changed for pixel format changes.
- * This, however isn't needed now because if there is a pixel format change,
- * we just assign a new hwpipe for it with a new SMP allocation. We might
- * eventually hit a condition where we would need to do a full modeset if
- * we run out of planes. There, we'd probably need to set mode_changed.
