Hello,

The main goal of this big cleanup series is to get rid of
nand_release(). I am always confused when it comes to use either
nand_cleanup() or nand_release() and I need to check the code in the
core, which is a sign of the API being badly designed.

Historically, there was a "nand_release()" helper only, doing the MTD
device unregistration and cleaning/freeing all objects belonging to
the NAND core. Later (v4.9), nand_cleanup() was been added to take
care of all the NAND cleanup, and was called directly by
nand_release(). This new helper was very useful to cleanup all the
NAND core objects in one go on _probe() error (after a successful
nand_scan()).

Unfortunately, because of the lack of symmetry in the API, a lot of
people also used nand_release wrongly in the _probe() error path.

So now, instead of:

        nand_release(chip);

I would like people to use:

        ret = mtd_device_unregister(mtd);
	WARN_ON(ret);
	nand_cleanup(chip);

Note: as it is currently not possible to handle properly an error on
mtd_device_unregister(), WARN_ON() will at least inform the user.

All of you receiving this cover letter will at least receive one patch
applying this change to the driver you are maintaining.

Thanks,
Miquèl

Note: as the modification are minor, I did not Cc: everybody in the
rest of the series due to the amount of patches.

Changes in v2:
* Removed Piotr and Xiaolei from the Cc: list (bouncing e-mails).
* Fixed a forgotten kfree() in the cs553x_nand.c driver remove path.
* Added Masahiro's Acked-by.
* Rebased on top of the latest nand/next.
* Added Christophe's Reviewed-by.
* Fixed a commit title with "ranwnand" in it.

This helper is not very useful and very often people get confused:
they use nand_release() instead of nand_cleanup().

Let's stop using nand_release() by calling mtd_device_unregister() and
nand_cleanup() directly.

This helper is not very useful and very often people get confused:
they use nand_release() instead of nand_cleanup().

Let's stop using nand_release() by calling mtd_device_unregister() and
nand_cleanup() directly.

Not sure nand_cleanup() is the right function to call here but in any
case it is not nand_release(). Indeed, even a comment says that
calling nand_release() is a bit of a hack as there is no MTD device to
unregister. So switch to nand_cleanup() for now and drop this
comment.

There is no Fixes tag applying here as the use of nand_release()
in this driver predates by far the introduction of nand_cleanup() in
commit d44154f969a4 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources")
which makes this change possible. However, pointing this commit as the
culprit for backporting purposes makes sense even if it did not intruce
any bug.

This helper is not very useful and very often people get confused:
they use nand_release() instead of nand_cleanup().

Let's stop using nand_release() by calling mtd_device_unregister() and
nand_cleanup() directly.

nand_release() is supposed be called after MTD device registration.
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 d44154f969a4 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources")
which makes this change possible. Hence, pointing it as the commit to
fix for backporting purposes, even if this commit is not introducing
any bug makes sense.

This helper is not very useful and very often people get confused:
they use nand_release() instead of nand_cleanup().

Let's stop using nand_release() by calling mtd_device_unregister() and
nand_cleanup() directly.

nand_release() is supposed be called after MTD device registration.
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 d44154f969a4 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources")
which makes this change possible. However, pointing this commit as the
culprit for backporting purposes makes sense even if this commit is not
introducing any bug.

This helper is not very useful and very often people get confused:
they use nand_release() instead of nand_cleanup().

Let's stop using nand_release() by calling mtd_device_unregister() and
nand_cleanup() directly.

All initialized and registered devices should be listed somewhere so
that we can unregister/free them in the _remove() path.

This patch is not a fix per-se but is needed to apply three other
fixes coming right after, explaining the Fixes/Cc: stable tags.

nand_release() is supposed be called after MTD device registration.
Here, only nand_scan() happened, so use nand_cleanup() instead.

While at it, be consistent and move the function call in the error
path thanks to a goto statement.

On error, the oxnas probe path just frees the device which failed and
aborts the probe, leaving unreleased resources.

Fix this situation by calling mtd_device_unregister()/nand_cleanup()
on these.

oxnans_nand_remove() should release all MTD devices and clean all NAND

nand_cleanup() is supposed to be called on error after a successful
call to nand_scan() to free all NAND resources.

There is no real Fixes tag applying here as the use of nand_release()
in this driver predates by far the introduction of nand_cleanup() in
commit d44154f969a4 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources")
which makes this change possible, hence pointing it as the commit to
fix for backporting purposes, even if this commit is not introducing
any bug.

This helper is not very useful and very often people get confused:
they use nand_release() instead of nand_cleanup().

Let's stop using nand_release() by calling mtd_device_unregister() and
nand_cleanup() directly.

nand_release() is supposed be called after MTD device registration.
Here, only nand_scan() happened, so use nand_cleanup() instead.

There is no Fixes tag applying here as the use of nand_release()
in this driver predates by far the introduction of nand_cleanup() in
commit d44154f969a4 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources")
which makes this change possible. However, pointing this commit as the
culprit for backporting purposes makes sense.

This helper is not very useful and very often people get confused:
they use nand_release() instead of nand_cleanup().

Let's stop using nand_release() by calling mtd_device_unregister() and
nand_cleanup() directly.

nand_release() is supposed be called after MTD device registration.
Here, only nand_scan() happened, so use nand_cleanup() instead.

nand_release() is supposed be called after MTD device registration.
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 by far the introduction of nand_cleanup() in
commit d44154f969a4 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources")
which makes this change possible. However, pointing this commit as the
culprit for backporting purposes makes sense even if this commit is not
introducing any bug.

This helper is not very useful and very often people get confused:
they use nand_release() instead of nand_cleanup().

Let's stop using nand_release() by calling mtd_device_unregister() and
nand_cleanup() directly.

This helper is not very useful and very often people get confused:
they use nand_release() instead of nand_cleanup().

Now that all drivers have been converted to do not use nand_release()
anymore, let's remove this helper.
