ata: drop owner assignment from platform_drivers

2014-10-20T14:20:17+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

ata: pata_imx: Use the SIMPLE_DEV_PM_OPS() macro

2014-10-05T02:06:57+00:00

Using the SIMPLE_DEV_PM_OPS() macro can make the code shorter and cleaner.

ata: use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable in host drivers

2014-05-10T02:37:49+00:00

This patch fixes host drivers to use CONFIG_PM_SLEEP instead of CONFIG_PM
where applicable.  Benefits of this change:

* unused code is not being compiled in for CONFIG_PM=y, CONFIG_PM_SLEEP=n
  and CONFIG_PM_RUNTIME=y configurations

* easier transition to use struct dev_pm_ops and SIMPLE_DEV_PM_OPS() in
  the future

* more consistent code (there are host drivers which are using the correct
  CONFIG_PM_SLEEP checks already)

The patch leaves the core libata code and ->port_[suspend,resume] support
in sata_[inic162x,nv,sil24].c alone for now.

Merge branch 'for-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

2014-03-31T22:27:37+00:00

Pull libata updates from Tejun Heo:
 "A lot of activities on libata side this time.

   - A lot of changes around ahci.  Various embedded platforms are
     implementing ahci controllers.  Some were built atop ahci_platform,
     others were doing their own things.  Hans made some structural
     changes to libahci and librarized ahci_platform so that ahci
     platform drivers can share more common code.  A couple platform
     drivers are added on top of that and several are added to replace
     older drivers which were doing their own things (older ones are
     scheduled to be removed).

   - Dan finishes the patchset to make libata PM operations
     asynchronous.  Combined with one patch being routed through scsi,
     this should speed resume measurably.

   - Various fixes and cleanups from Bartlomiej and others"

ata: pata_imx: fix devm_ioremap_resource() return value checking

2014-03-14T18:30:28+00:00

devm_ioremap_resource() returns a pointer to the remapped memory or
an ERR_PTR() encoded error code on failure.  Fix the check inside
pata_imx_probe() accordingly.

pata_imx: Propagate the real error code on platform_get_irq() failure

2014-02-18T22:39:54+00:00

No need to return a 'fake' return value on platform_get_irq() failure.

Just return the error code itself instead.

Also, change the error condition to irq < 0, so that only negative values
are treated as errors.

pata_imx: Use devm_ioremap_resource() to simplify code

2014-02-18T22:39:54+00:00

Using devm_ioremap_resource() can lead to code simplication, as we don't need
to explicitily check for error returned by platform_get_resource().

Also, no need to print an error message when devm_ioremap_resource() fails,
as the OOM code code will shout loudly on such condition.

ata: delete non-required instances of include

2014-02-13T21:40:56+00:00

None of these files are actually using any __init type directives
and hence don't need to include .  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.
