On the older-gen 32-bit SoCs the meson-saradc driver is used to read the
SoC temperature. This requires reading calibration data from the eFuse.
Looking up the calibration data nvmem-cell requires the OF device_node
pointer to be available in the struct device which is passed to
devm_nvmem_cell_get(). This however got lost with commit 8cb631ccbb1952
("iio: Remove superfluous of_node assignments") from indio_dev->dev. As
devm_nvmem_cell_get() is called in the initialization phase the
device_node is not yet available because the NVMEM cell is looked up
before iio_device_register() is called (which would then set the
device_node automatically).
Use the parent device to look up the NVMEM cell instead to fix this
issue.

One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv() data.
This data is allocated with kzalloc so no data can leak apart
from previous readings.
The explicit alignment of ts is necessary to ensure correct padding
on architectures where s64 is only 4 bytes aligned such as x86_32.

iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses a 32 byte array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv() data with alignment
explicitly requested. This data is allocated with kzalloc so no
data can leak apart from previous readings. The explicit alignment
isn't technically needed here, but it reduced fragility and avoids
cut and paste into drivers where it will be needed.
If we want this in older stables will need manual backport due to
driver reworks.

There's a bit of confusion on the matching pairs of poll vs double poll,
depending on if the request is a pure poll (IORING_OP_POLL_ADD) or
poll driven retry.
Add io_poll_get_double() that returns the double poll waitqueue, if any,
and io_poll_get_single() that returns the original poll waitqueue. With
that, remove the argument to io_poll_remove_double().
Finally ensure that wait->private is cleared once the double poll handler
has run, so that remove knows it's already been seen.

The ioreadX() helpers have inconsistent interface. On some architectures
void *__iomem address argument is a pointer to const, on some not.
Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.

Patch series "iomap: Constify ioreadX() iomem argument", v3.
The ioread8/16/32() and others have inconsistent interface among the
architectures: some taking address as const, some not.
It seems there is nothing really stopping all of them to take pointer to
const.
This patch (of 4):
The ioreadX() and ioreadX_rep() helpers have inconsistent interface. On
some architectures void *__iomem address argument is a pointer to const,
on some not.
Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.

80 is above array bounds of 'char[26]' [-Warray-bounds]
: "0" (__dest), "1" (__src), "r" (__src+__n)
~~~~~^~~~
In general, strncpy() should behave like below.
char dest[10];
char *src = "12345";
strncpy(dest, src, 10);
// dest = {'1', '2', '3', '4', '5',
'\0','\0','\0','\0','\0'}
But, current SH strnpy() has 2 issues.
1st is it will access to out-of-memory (= src + 10).
2nd is it needs big fixup for it, and maintenance __asm__
code is difficult.
To solve these issues, this patch simply uses generic strncpy()
instead of architecture specific one.
