yes, we can feed the address of the first member of structure
to kmem_cache_free(), but let's do it in an obviously safe way.

A lot of ->destroy_inode() instances end with call_rcu() of a callback
that does RCU-delayed part of freeing. Introduce a new method for
doing just that, with saner signature.
Rules:
->destroy_inode ->free_inode
f g immediate call of f(),
RCU-delayed call of g()
f NULL immediate call of f(),
no RCU-delayed calls
NULL g RCU-delayed call of g()
NULL NULL RCU-delayed default freeing
IOW, NULL ->free_inode gives the same behaviour as now.
Note that NULL, NULL is equivalent to NULL, free_inode_nonrcu; we could
mandate the latter form, but that would have very little benefit beyond
making rules a bit more symmetric. It would break backwards compatibility,
require extra boilerplate and expected semantics for (NULL, NULL) pair
would have no use whatsoever...

symlink body shouldn't be freed without an RCU delay. Switch apparmorfs
to ->destroy_inode() and use of call_rcu(); free both the inode and symlink
body in the callback.

A collection of fixes from the last few weeks. Most of them are smaller
tweaks and fixes to DT and hardware descriptions for boards. Some of the
more significant ones are:
- eMMC and RGMII stability tweaks for rk3288
- DDC fixes for Rock PI 4
- Audio fixes for two TI am335x eval boards
- D_CAN clock fix for am335x
- Compilation fixes for clang
- !SMP compilation fix for one of the new platforms this release (milbeaut)
- A revert of a gpio fix for nomadik that instead was fixed in the gpio
subsystem
- Whitespace fix for the DT JSON schema (no tabs allowed)

Per Linus Walleij:
Dear ARM SoC maintainers,
can you please revert this patch. It was the wrong solution to the
wrong problem, and I must have acted in stress. Andrey fixed the
real bug in a proper way in these commits:
commit e5545c94e4
"gpio: of: Check propname before applying "cs-gpios" quirks"
commit 7ce40277bf
