[PATCH 0/5] drivers: bus: omap_l3: Conversion to devm_*

[PATCH 0/5] drivers: bus: omap_l3: Conversion to devm_*

[Peter Ujfalusi]

Hi,

Cleanup of platform probe and remove (removing the remove function at the end)
with converting the driver to use the devm_* versions kzalloc, ioremap and
request_irq. 

This is a resend of an old series which I found when doing some spring cleanup
on my HDD:
http://www.spinics.net/lists/linux-omap/msg90531.html

Regards,
Peter

[PATCH 2/5] drivers: bus: omap_l3: Convert to use devm_request_and_ioremap()

[Peter Ujfalusi]

We can then remove the iounmap() calls from probe and remove.
Since the driver requests the resources via index we can do the mem resource
request within a for loop.

[PATCH 5/5] drivers: bus: omap_l3: Change pr_crit() to dev_err() when IRQ request fails

[Peter Ujfalusi]

Use dev_err() which will going to print the driver's name as well and the
KERN_ERR level is sufficient in this case (we also print via dev_err when
there is an error with the mem resources)

No need to check "res". devm_request_and_ioremap() do all for us.

Ahh, I messed up this with devm_ioremap_resource().
However, if there is reason to use devm_request_and_ioremap() here?

devm_request_and_ioremap() is just a wrapper for devm_ioremap_resource(). It
returns NULL in case of error (eats up the error code at the same time).
I don't have strong preference on this so I can change it to
devm_ioremap_resource()

Thanks Peter. All patches looks fine to my eyes. In the last patch wher
you are changing the error level is bit debatable but I agree with you.

[PATCH 0/5] drivers: bus: omap_l3: Conversion to devm_*

[Peter Ujfalusi]

Hi,

Cleanup of platform probe and remove (removing the remove function at the end)
with converting the driver to use the devm_* versions kzalloc, ioremap and
request_irq.

Regards,
Peter
