can you drop this patch from _all_ stable patches, it was reverted already
in the pull-request to Linus. Thank you.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea. [ RFC1925, 2.3 ]
In order to set the rate range of a hw sunxi_ccu_probe calls
hw_to_ccu_common() assuming all entries in desc->ccu_clks are contained
in a ccu_common struct. This assumption is incorrect and, in
consequence, causes invalid pointer de-references.
Remove the faulty call. Instead, add one more loop that iterates over
the ccu_clks and sets the rate range, if required.

Robert, could you please test if this fixes the issue you reported.
I'm CC'ing Måns here, because he observed some strange behavior [1] with
the original patch. Is it possible for you to look into if this patch
fixes your issue without the need for the following (seemingly
unrelated) patches:
cedb7dd193f6 "drm/sun4i: hdmi: Convert encoder to atomic"
9ca6bc246035 "drm/sun4i: hdmi: Move mode_set into enable"
Thanks,
Frank

Subject: media: venus: fix use after free in vdec_close
Author: Dikshita Agarwal <quic_dikshita(a)quicinc.com>
Date: Thu May 9 10:44:29 2024 +0530
There appears to be a possible use after free with vdec_close().
The firmware will add buffer release work to the work queue through
HFI callbacks as a normal part of decoding. Randomly closing the
decoder device from userspace during normal decoding can incur
a read after free for inst.
Fix it by cancelling the work in vdec_close.

Subject: [PATCH] efi/x86: Free EFI memory map only when installing a new one.
The logic in __efi_memmap_init() is shared between two different
execution flows:
- mapping the EFI memory map early or late into the kernel VA space, so
that its entries can be accessed;
- the x86 specific cloning of the EFI memory map in order to insert new
entries that are created as a result of making a memory reservation
via a call to efi_mem_reserve().
In the former case, the underlying memory containing the kernel's view
of the EFI memory map (which may be heavily modified by the kernel
itself on x86) is not modified at all, and the only thing that changes
is the virtual mapping of this memory, which is different between early
and late boot.
In the latter case, an entirely new allocation is created that carries a
new, updated version of the kernel's view of the EFI memory map. When
installing this new version, the old version will no longer be
referenced, and if the memory was allocated by the kernel, it will leak
unless it gets freed.
The logic that implements this freeing currently lives on the code path
that is shared between these two use cases, but it should only apply to
the latter. So move it to the correct spot.
While at it, drop the dummy definition for non-x86 architectures, as
that is no longer needed.
