[PATCH 00/15] Convert to use devm_ioremap_resource

[Tushar Behera]

These are the remaining instances of devm_request_and_ioremap. Convert
them to use devm_ioremap_resource as introduced by commit
75096579c3ac ("lib: devres: Introduce devm_ioremap_resource()).
Patches 1 to 13 remove occurrences of devm_request_and_ioremap.
Patch 14 modifies one comment that speaks about devm_request_and_ioremap.
Patch 15 removes the definition of devm_request_and_ioremap which
should only be applied if all other pathces are merged.

You may remove the above error message as devm_ioremap_resource prints
its own error messages.

Are the patches going over the individual subsystem maintainers?

I'm taking the ones for my subsystem(s), the last one should probably go
in after 3.11-rc1 is released, in order to ensure no remaining in-tree
users of the function are still around.

IS_ERR() check on the return value of devm_ioremap_resource produces
following sparse warning. This is because of the __iomem address space
attribute. How should we fix this?

This is a known issue since the time devm_ioremap_resource was
introduced. Thierry had already submitted some fixes for this.
I am not sure if they have been applied yet.

You may remove the above error message as devm_ioremap_resource prints
its own error messages.

There are a few other error messages in the driver (related to

The comment was on removal of the error message during
devm_ioremap_resource() error check . Since there are a few other error
messages in the driver (related to devm_ioremap_nocache) in the same
format, I prefer to leave this error message right now.

There were no other comments.

So we should say the same thing repeatedly?  That seems silly.  That
seems silly.   It's like the contentless pings issue...

The intention was to make resource usage more consistent with the new
devm_ioremap_resource(). Part of the consistency involved to move all
error messages into the function so that callers shouldn't have to
worry about them anymore.

So I agree with Mark that there's really no use in keeping a second copy
of the error message.

[PATCH V2 11/15] regulator: ti-abb: Convert to use devm_ioremap_resource

[Tushar Behera]

Commit 75096579c3ac ("lib: devres: Introduce devm_ioremap_resource()")
introduced devm_ioremap_resource() and deprecated the use of
devm_request_and_ioremap().

While at it, remove the error message as devm_ioremap_resource prints a similar
error message.

I've applied this.  In future please do remember that if you're not
sending a patch series you shouldn't mark it as being part of one,
people will only wonder where the rest of the series is and miss things.
You haven't sent me 15 patches, you've sent me a single patch.

This patch does a little more than just conversion. May that change
could be mentioned here.

This print is not needed as devm_ioremap_resource prints its own messages.

It provides a little more information regarding the port and lane number
which might be useful in debugging.

I was not sure about the default error value for port->base, hence I
replicated the old behaviour.

[PATCH V2 6/6] pci: mvebu: Convert to use devm_ioremap_resource

[Tushar Behera]

Commit 75096579c3ac ("lib: devres: Introduce devm_ioremap_resource()")
introduced devm_ioremap_resource() and deprecated the use of
devm_request_and_ioremap().

While at it, modify mvebu_pcie_map_registers() to propagate error code.

Thomas has a bunch of mvebu patches in the pipeline, so I assume he
will incorporate this if appropriate.  I don't want to put it in my
tree and cause conflicts with his changes.  Let me know if I should do
something else here.

We have the MBus DT patches, to say the least.
Not sure if it conflicts with this and how we should handle it in that
case.

I don't really have that many pci-mvebu.c patches in the pipeline
actually. The only one I have is to enable MSI support, and it's a
fairly light one that should not conflict too badly with this one.

Therefore, Bjorn, I believe this patch could go through your tree,
either for 3.11 or 3.12 as you prefer.

[PATCH 15/15] lib: devres: Remove deprecated devm_request_and_ioremap

[Tushar Behera]

Now that all the users of devm_request_and_ioremap have been converted
to use devm_ioremap_resource, remove the definition.

Also remove the entries from Documentation.

This is a function which was exported to the drivers including
third-party drivers.
I suggest to mark it as __deprecated and wait couple of release cycles.

That doesn't matter, we've cleaned up all in-kernel users of it, so we
can safely delete it.
