should return NULL instead. The error pointer code in
__devm_auxiliary_device_create() was left over from the first version.
Update it to use NULL. No callers have been merged yet, so that makes
this change simple and self contained.

Add test cases for static and dynamic minor number allocation and
deallocation.
While at it, improve description and test suite name.
Some of the cases include:
- that static and dynamic allocation reserved the expected minors.
- that registering duplicate minors or duplicate names will fail.
- that failing to create a sysfs file (due to duplicate names) will
deallocate the dynamic minor correctly.
- that dynamic allocation does not allocate a minor number in the static
range.
- that there are no collisions when mixing dynamic and static allocations.
- that opening devices with various minor device numbers work.
- that registering a static number in the dynamic range won't conflict with
a dynamic allocation.
This last test verifies the bug fixed by commit 6d04d2b554 ("misc:
misc_minor_alloc to use ida for all dynamic/misc dynamic minors") has not
regressed.

When this was first reported [1], the possibility of having sufficient
number of dynamic misc devices was theoretical, in the case of dlm driver.
In practice, its userspace never created more than one device.
What we know from commit ab760791c0 ("char: misc: Increase the maximum
number of dynamic misc devices to 1048448"), is that the miscdevice
interface has been used for allocating more than the single-shot devices it
was designed for. And it is not only coresight_tmc, but many other drivers
are able to create multiple devices.
On systems like the ones described in the above commit, it is certain that
the dynamic allocation will allocate certain reserved minor numbers,
leading to failures when a later driver tries to claim its reserved number.
Instead of excluding the historically statically allocated range from
dynamic allocation, restrict the latter to minors above 255. That also
removes the need for DYNAMIC_MINORS and the convolution in allocating minor
numbers, simplifying the code.
Since commit ab760791c0 ("char: misc: Increase the maximum number of
dynamic misc devices to 1048448") has been applied, such range is already
possible. And given such devices already need to be dynamically created,
there should be no systems where this might become a problem.

cardreader enables its PCI device with pcim_enable_device(). This,
implicitly, switches the function pci_request_regions() into managed
mode, where it becomes a devres function.
The PCI subsystem wants to remove this hybrid nature from its
interfaces. To do so, users of the aforementioned combination of
functions must be ported to non-hybrid functions.
Moreover, since both functions are already managed in this driver, the
calls to pci_release_regions() are unnecessary.
Remove the calls to pci_release_regions().
Replace the call to sometimes-managed pci_request_regions() with one to

Depending on the driver, the acquisition buffer is allocated either from
normal memory, or from DMA coherent memory. For normal memory, the
buffer is allocated as individual pages, but for DMA coherent memory, it
is allocated as a single block. Prior to commit e36472145a ("staging:
comedi: use dma_mmap_coherent for DMA-able buffer mmap"), the buffer was
allocated as individual pages for DMA coherent memory too, but that was
changed to allocate it as a single block to allow `dma_mmap_coherent()`
to be used to mmap it, because that requires the pages being mmap'ed to
be contiguous.
This patch allocates the buffer from DMA coherent memory a page at a
time again, and works around the limitation of `dma_mmap_coherent()` by
calling it in a loop for each page, with temporarily modified `vm_start`
and `vm_end` values in the VMA. (The `vm_pgoff` value is 0.)

Now that all the code that accesses the Comedi buffer data does so
page-by-page, using the `virt_addr` member of `struct comedi_buf_page`
to point to the data of each page, do not linearly map the buffer into
vmalloc address space (pointed to by the `prealloc_buf` member of
`struct comedi_async`). That was only done for convenience, but was not
done for those drivers that need a DMA coherent buffer, which is
allocated in a single chunk. Remove the `prealloc_buf` member as it is
no longer used.

The aim is to get rid of the `prealloc_buf` member of `struct
comedi_async` and access the buffer contents on a page-by-page basis
using the addresses in the `virt_addr` member of `struct
comedi_buf_page`. This will allow us to eliminate a `vmap()` that maps
the whole buffer.
Since the buffer pages have non-consecutive `virt_addr` addresses in
virtual memory (except for drivers using DMA), change the loops that
access buffer data to access it page-by-page.

On buffer change, the driver informs the mite module about the buffer
change and then it fills the buffer with byte value `0xaa` using
`memset()`. Do not bother filling the buffer. None of the other Comedi
drivers do this.
The aim is to get rid of the `prealloc_buf` member of `struct
comedi_async` (which is from a `vmap()` covering the whole buffer in
those Comedi drivers that do not use DMA), and use the per-buffer-page
addresses from the `virt_addr` member of `struct comedi_buf_page` to
access the buffer contents instead.
(If necessary, we could add a `comedi_buf_memset()` function to fill the
buffer with a byte value, but it's not worth it in this case.)

Currently, the driver only has the F1 OneXFly variant, which was based
on the 7000 AMD platform. Add its special editions: F1 EVA-01, F1 OLED.
F1 OLED might have been a dev unit, but it is supported by OneXConsole
with the same features so add it. Then add the F1L variant which is
based on the 8000 AMD platform and the F1Pro and its special edition
EVA-02.
One might ask why not just fuzzy match. Well, EVA-02 is a variant of
F1Pro which is a Strix Point handheld, but does not have F1Pro in its
name. This makes it risky to fuzzy match, as special variants in the
future from different platforms might not have the same feature set
or registers.
By happenstance, all current devices use the same registers. For the
charge limitting feature on this series, only F1Pro/X1 (AMD) were
released with it, but OneXPlayer is providing bios updates for F1, F1L,
X1 Mini units that use the same register, so treat all of them the same.

Currently, the oxp-sensors driver fuzzy matches the X1 variants. Luckily,
X1 and X1 mini share most hardware features so this works. However, they
are completely different product lines, and there is an expectation that
OneXPlayer will release more devices in the X1 line that may have
differences.
Therefore, distinguish the 3 devices that currently exist in the market.
These are the OneXPlayer X1 AMD and Intel variants, and the X1 mini which
only has an AMD variant. As far as registers go, all three support the
current driver functionality.
