The three bugs are here:
__func__, s3a_buf->s3a_data->exp_id);
__func__, md_buf->metadata->exp_id);
__func__, dis_buf->dis_data->exp_id);
The list iterator 's3a_buf/md_buf/dis_buf' will point to a bogus
position containing HEAD if the list is empty or no element is found.
This case must be checked before any use of the iterator, otherwise
it will lead to a invalid memory access.
To fix this bug, add an check. Use a new variable '*_iter' as the
list iterator, while use the old variable '*_buf' as a dedicated
pointer to point to the found element.

The use of kmap() is being deprecated in favor of kmap_local_page()
where it is feasible. The same is true for kmap_atomic().
In file pci/hmm/hmm.c, function hmm_store() test if we are in atomic
context and, if so, it calls kmap_atomic(), if not, it calls kmap().
First of all, in_atomic() shouldn't be used in drivers. This macro
cannot always detect atomic context; in particular, it cannot know
about held spinlocks in non-preemptible kernels.
Notwithstanding what it is said above, this code doesn't need to care
whether or not it is executing in atomic context. It can simply use
kmap_local_page() / kunmap_local() that can instead do the mapping /
unmapping regardless of the context.
With kmap_local_page(), the mapping is per thread, CPU local and not
globally visible. Therefore, hmm_store()() is a function where the use
of kmap_local_page() in place of both kmap() and kmap_atomic() is
correctly suited.
Convert the calls of kmap() / kunmap() and kmap_atomic() /
kunmap_atomic() to kmap_local_page() / kunmap_local() and drop the
unnecessary tests which test if the code is in atomic context.

Although all DSS belong to a single pool on Xe_HP platforms (i.e.,
they're not organized into slices from a topology point of view), we do
still need to pass 'group' and 'instance' targets when steering register
accesses to a specific instance of a per-DSS multicast register. The
rules for how to determine group and instance IDs (which previously used
legacy terms "slice" and "subslice") varies by platform. Some platforms
determine steering by gslice membership, some platforms by cslice
membership, and future platforms may have other rules.
Since looping over each DSS and performing steered unicast register
accesses is a relatively common pattern, let's add a dedicated iteration
macro to handle this (and replace the platform-specific "instdone" loop
we were using previously. This will avoid the calling code needing to
figure out the details about how to obtain steering IDs for a specific
DSS.
Most of the places where we use this new loop are in the GPU errorstate
code at the moment, but we do have some additional features coming in
the future that will also need to loop over each DSS and steer some
register accesses accordingly.

Using simple bash script it was discovered that not all CCU registers
can be safely used for DFS, e.g.:
while true
do
devmem 0x3001030 4 0xb0003e02
devmem 0x3001030 4 0xb0001e02
done
Script above changes the GPU_PLL multiplier register value. While the
script is running, the user should interact with the user interface.
Using this method the following results were obtained:
| Register | Name | Bits | Values | Result |
| -- | -- | -- | -- | -- |
| 0x3001030 | GPU_PLL.MULT | 15..8 | 20-62 | OK |
| 0x3001030 | GPU_PLL.INDIV | 1 | 0-1 | OK |
| 0x3001030 | GPU_PLL.OUTDIV | 0 | 0-1 | FAIL |
| 0x3001670 | GPU_CLK.DIV | 3..0 | ANY | FAIL |
DVFS started to work seamlessly once dividers which caused the
glitches were set to fixed values.

Clang static analysis reports this representative issue
atomisp-ov2722.c:920:3: warning: 3rd function call
argument is an uninitialized value
dev_err(&client->dev, "sensor_id_high = 0x%x\n", high);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
high and low are only set when ov2722_read_reg() is successful.
Reporting the high value when there is an error is not
meaningful. The later read for low is not checked. high
and low are or-ed together and checked against a non zero
value.
Remove the unneeded error reporting for high. Initialize
high and low to 0 and use the id check to determine if
the reads were successful
The later read for revision is not checked. If it
fails the old high value will be used and the revision
will be misreported.
Since the revision is only reported and not checked or
stored it is not necessary to return if the read with
successful. This makes the ret variable unnecessary
so remove it.

These ioctls allow userspace to load custom programs into the ISP, which:
a) Seems dangerous
b) Cannot be used by opensource userspace since there is no FOSS code to
create such programs
b) These seem to be unused even by the Android closed source camera code
(they don't show up in a strace of the camera app)
So removing these seems be a good idea. Another reason to remove these is
that atomisp_acc_map() is the only user of the userptr functionality in
hmm_alloc(), so it gets in the way of further cleanups / simplification
of the hmm code.

Since we never register any pools, this is all dead code,
remove it.

There are no callers of this code atm; and looking at the atomisp
memory-management code if anything we want to make it simpler and
not re-introduce use of these pools, so remove the pool code.

Drop the ATOMISP_MAP_FLAG_CONTIGUOUS hmm_alloc flag. After the contiguous
flag removal done in previous patches in this series it is never set.
And hmm_alloc already did a WARN_ON on the flag and otherwise ignored it,
proving that contiguous support was already never used.

Drop the contiguous flag from struct ia_css_frame, it is always false /
not used.

Nothing ever sets the format to IA_CSS_FRAME_FORMAT_MIPI and
frame_init_mipi_plane() is the only code-path which ever sets
frame->contiguous to true.
Drop A_CSS_FRAME_FORMAT_MIPI support from ia_css_frame_init_planes()
as part of the removal of contiguous alloc support from the frame code.
