Nothing special here, except that this is the first time that we
automatically clean up something that's initialized with an explicit
driver call. But the cleanup was done at the very end of the release
sequence for all drivers, and that's still the case. At least without
more uses of drmm_ through explicit driver calls.
Also for this one we need drmm_kcalloc, so lets add those.
The motivation here is to allow us to remove the explicit calls to
drm_dev_fini() from all drivers.

The cleanup here is somewhat tricky, since we can't tell apart the
allocated minor index from 0. So register a cleanup action first, and
if the index allocation fails, unregister that cleanup action again to
avoid bad mistakes.
The kdev for the minor already handles NULL, so no problem there.
Hence add drmm_remove_action() to the drm_managed library.
v2: Make pointer math around void ** consistent with what Laurent
suggested.
v3: Use drmm_add_action_or_reset and remove drmm_remove_action. Noticed
because of some questions from Thomas. This also means we need to move
the drmm_add_action_or_reset helper earlier in the series.
v4: Uh ... fix slightly embarrassing bug CI spotted.

With this we can drop the final kfree from the release function.
The mock device in the selftests needed it's pci_device split
up from the drm_device. In the future we could simplify this again
by allocating the pci_device as a managed allocation too.
v2: I overlooked that i915_driver_destroy is also called in the
unwind code of the error path. There we need a drm_dev_put.
Similar for the mock object.
Now the problem with that is that the drm_driver->release callbacks
for both the real driver and the mock one assume everything has been
set up. Hence going through that path for a partially set up driver
will result in issues. Quickest fix is to disable the ->release() hook
until the driver is fully initialized, and keep the onion unwinding.
Long term would be cleanest to move everything over to drmm_ release
actions, but that's a lot of work for a big driver like i915. Plus
more core work needed first anyway.
v3: Fix i915_drm pointer wrangling in mock_gem_device. Also switch
over to start using drm_dev_put() to clean up even on the error path.
Aside I think the current error path is leaking the allocation.
v4: more fixes for intel-gfx-ci, some if it damage from v3 :-/

We have lots of these. And the cleanup code tends to be of dubious
quality. The biggest wrong pattern is that developers use devm_, which
ties the release action to the underlying struct device, whereas
all the userspace visible stuff attached to a drm_device can long
outlive that one (e.g. after a hotunplug while userspace has open
files and mmap'ed buffers). Give people what they want, but with more
correctness.
Mostly copied from devres.c, with types adjusted to fit drm_device and
a few simplifications - I didn't (yet) copy over everything. Since
the types don't match code sharing looked like a hopeless endeavour.
For now it's only super simplified, no groups, you can't remove
actions (but kfree exists, we'll need that soon). Plus all specific to
drm_device ofc, including the logging. Which I didn't bother to make
compile-time optional, since none of the other drm logging is compile
time optional either.
One tricky bit here is the chicken&egg between allocating your
drm_device structure and initiliazing it with drm_dev_init. For
perfect onion unwinding we'd need to have the action to kfree the
allocation registered before drm_dev_init registers any of its own
release handlers. But drm_dev_init doesn't know where exactly the
drm_device is emebedded into the overall structure, and by the time it
returns it'll all be too late. And forcing drivers to be able clean up
everything except the one kzalloc is silly.
Work around this by having a very special final_kfree pointer. This
also avoids troubles with the list head possibly disappearing from
underneath us when we release all resources attached to the
drm_device.
v2: Do all the kerneldoc at the end, to avoid lots of fairly pointless
shuffling while getting everything into shape.
v3: Add static to add/del_dr (Neil)
Move typo fix to the right patch (Neil)
v4: Enforce contract for drmm_add_final_kfree:
Use ksize() to check that the drm_device is indeed contained somewhere
in the final kfree(). Because we need that or the entire managed
release logic blows up in a pile of use-after-frees. Motivated by a
discussion with Laurent.
v5: Review from Laurent:
- %zu instead of casting size_t
- header guards
- sorting of includes
- guarding of data assignment if we didn't allocate it for a NULL
pointer
- delete spurious newline
- cast void* data parameter correctly in ->release call, no idea how
this even worked before
v6: Review from Sam
- Add the kerneldoc for the managed sub-struct back in, even if it
doesn't show up in the generated html somehow.
- Explain why __always_inline.
- Fix bisectability around the final kfree() in drm_dev_relase(). This
is just interim code which will disappear again.
- Some whitespace polish.
- Add debug output when drmm_add_action or drmm_kmalloc fail.
v7: My bisectability fix wasn't up to par as noticed by smatch.
v8: Remove unecessary {} around if else
v9: Use kstrdup_const, which requires kfree_const and introducing a free_dr()
helper (Thomas).
v10: kfree_const goes boom on the plain "kmalloc" assignment, somehow
we need to wrap that in kstrdup_const() too!! Also renumber revision
log, I somehow reset it midway thruh.

For two reasons:
- The driver core clears this already for us after we're unloaded in
__device_release_driver().
- It's way too late, the drm_device ->release callback might massively
outlive the underlying physical device, since a drm_device can be
kept alive by open drm_file or well really anything else userspace
is still hanging onto. So if we clear this ourselves, we should
clear it in the pci ->remove callback, not in the drm_device
->release callback.

This is actually desired behaviour because result of this function

format conversion).
In order to clear misunderstandings, let's rework
