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.Signed-off-by: Bartlomiej Zolnierkiewicz

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"

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.Signed-off-by: Bartlomiej Zolnierkiewicz

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.Signed-off-by: Fabio Estevam

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.Signed-off-by: Fabio Estevam

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.Cc: linux-ide@vger.kernel.org

Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.Also, unnecessary dev_set_drvdata() is removed, because the driver core
clears the driver data to NULL after device_release or on probe failure.Signed-off-by: Jingoo Han

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.Cc: Bill Pemberton

Add basic support for pata on iMX. It has been tested only on imx51.
SDMA support will probably be added later so this version supports only
PIO.v2:
- enable only when needed IORDY
- use dev_get_drvdata
v3:
- add missing clk_put() calls
- use platform_get_irq()
- fix resume code to avoid disabling IORDY on resume
v4:
- Remove EXPERIMENTAL and switch to depends on ARCH_MXC
- Use devm_kzalloc()
- make clock a must-have
- Use only 1 ioremapSigned-off-by: Arnaud Patard
