After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/mtd to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

remove callbacks to return void. Comes next (in number of changes) Kees'
additional structures annotations to improve the sanitizers. The usual
amount of cleanups apply.
About the more substancial contribution, one main function of the
partitions core could return an error which was not checked, this is now
fixed. On the bindings side, fixed partitions can now have a compression
property. Finally, an erroneous situation is now always avoided in the
MAP RAM driver.
* CFI
A several years old byte swap has been fixed.
* NAND
The subsystem has, as usual, seen a bit of cleanup being done this
cycle, typically return values of platform_get_irq() and
devm_kasprintf(). There is also a better ECC check in the Arasan
driver. This comes with smaller misc changes.
In the SPI-NAND world there is now support for Foresee F35SQA002G,
Winbond W25N and XTX XT26 chips.
* SPI NOR
For SPI NOR we cleaned the flash info entries in order to have
them slimmer and self explanatory. In order to make the entries
as slim as possible, we introduced sane default values so that
the actual flash entries don't need to specify them. We now use
a flexible macro to specify the flash ID instead of the previous
INFOx() macros that had hardcoded ID lengths.
Instead of:
- { "w25q512nwm", INFO(0xef8020, 0, 64 * 1024, 0)
- OTP_INFO(256, 3, 0x1000, 0x1000) },
We now use:
+ .id = SNOR_ID(0xef, 0x80, 0x20),
+ .name = "w25q512nwm",
+ .otp = SNOR_OTP(256, 3, 0x1000, 0x1000),
We also removed some flash entries: the very old Catalyst
SPI EEPROMs that were introduced once with the SPI-NOR subsystem,
and a Fujitsu MRAM. Both should use the at25 EEPROM driver.
The latter even has device tree bindings for the at25 driver.
We made sure that the conversion didn't introduce any unwanted
changes by comparing the .rodata segment before and after the
conversion. The patches landed in linux-next immediately after
v6.6-rc2, we haven't seen any regressions yet.
Apart of the autumn cleaning we introduced a new flash entry,
at25ff321a, and added block protection support for mt25qu512a.

As part of that merge prepping Arm DT support 13 years ago, they

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

of_match_ptr() either expands to NULL if !CONFIG_OF, or is transparent
otherwise. There are several drivers using this macro which keep their
of_device_id array enclosed within an #ifdef CONFIG_OF check, these are
considered fine. However, When misused, the of_device_id array pointed
by this macro will produce a warning because it is finally unused when
compiled without OF support.
A number of fixes are possible:
- Always depend on CONFIG_OF, but this will not always work and may
break boards.
- Enclose the compatible array by #ifdef's, this may save a bit of
memory but will reduce build coverage.
- Tell the compiler the array may be unused, if this can be avoided,
let's not do this.
- Just drop the macro, setting the of_device_id array for a non OF
enabled platform is not an issue, it will just be unused.
The latter solution seems the more appropriate, so let's use it.

The ECC engine on the JZ4740 SoC requires the ECC data to be read before
the page; using the default page reading function does not work. Indeed,
the old JZ4740 NAND driver (removed in 5.4) did use the 'OOB first' flag
that existed back then.
Use the newly created nand_read_page_hwecc_oob_first() to address this
issue.
This issue was not found when the new ingenic-nand driver was developed,
most likely because the Device Tree used had the nand-ecc-mode set to
"hw_oob_first", which seems to not be supported anymore.

Here, only nand_scan() happened, so use nand_cleanup() instead.
There is no real Fixes tag applying here as the use of nand_release()
in this driver predates the introduction of nand_cleanup() in
commit d44154f969 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources")
which makes this change possible. Hence, pointing it as the commit to

Each iteration of for_each_child_of_node puts the previous node, but in
the case of a return from the middle of the loop, there is no put, thus
causing a memory leak. Hence add an of_node_put before the return.
Issue found with Coccinelle.

If MTD_NAND_JZ4780 is y and MTD_NAND_JZ4780_BCH is m,
which select CONFIG_MTD_NAND_INGENIC_ECC to m, building fails:
drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_remove':
ingenic_nand.c:(.text+0x177): undefined reference to `ingenic_ecc_release'
drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_ecc_correct':
ingenic_nand.c:(.text+0x2ee): undefined reference to `ingenic_ecc_correct'
To fix that, the ingenic_nand and ingenic_ecc modules have been fused
into one single module.
- The ingenic_ecc.c code is now compiled in only if
$(CONFIG_MTD_NAND_INGENIC_ECC) is set. This is now a boolean instead
of tristate.
- To avoid changing the module name, the ingenic_nand.c file is moved to
ingenic_nand_drv.c. Then the module name is still ingenic_nand.
- Since ingenic_ecc.c is no more a module, the module-specific macros
have been dropped, and the functions are no more exported for use by
the ingenic_nand driver.

This list is a mess, while some items should probably not be in the
raw/ sub-directory, others are definitely at the right place but not
with the right description. Write uniform titles and group IPs by
vendor.
NAND controllers will appear under the list named "Raw/parallel NAND
flash controllers" while the other drivers will appear under
"Misc". Software ECC engines will later be moved out of the raw/
directory.

The ingenic-nand driver uses an API provided by the jz4780-bch driver.
This makes it difficult to support other SoCs in the jz4780-bch driver.
To work around this, we separate the API functions from the SoC-specific
code, so that these API functions are SoC-agnostic.
