ata:sata_nv - Change 1 to true for bool type variable.

2015-05-26T00:06:55+00:00

The variable swncq_enabled is bool type. Hence initialize it
with true instead of 1.

ata: remove deprecated use of pci api

2015-04-08T14:55:05+00:00

Replace occurences of the pci api by appropriate call to the dma api.

A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr)

scsi: drop reason argument from ->change_queue_depth

2014-11-24T13:45:27+00:00

Drop the now unused reason argument from the ->change_queue_depth method.
Also add a return value to scsi_adjust_queue_depth, and rename it to
scsi_change_queue_depth now that it can be used as the default
->change_queue_depth implementation.

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.

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.

ata: use pci_get_drvdata()

2013-06-03T05:22:03+00:00

Use the wrapper function for getting the driver data using pci_dev
instead of using dev_get_drvdata() with &pdev->dev, so we can directly
pass a struct pci_dev.  This is a purely cosmetic change.

ata: use module_pci_driver

2012-07-25T19:12:11+00:00

This patch converts the drivers in drivers/ata/* to use module_pci_driver()
macro which makes the code smaller and a bit simpler.

module_param: make bool parameters really bool (drivers & misc)

2012-01-12T23:02:20+00:00

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

ata: Add and use ata_print_version_once

2011-07-23T21:57:36+00:00

Use a single mechanism to show driver version.
Reduces text a tiny bit too.

Remove uses of static int printed_version
Add and use ata_print_version(const struct device *, const char *ver)
and ata_print_version_once.

ata: Convert ata__printk(KERN_ to ata__

2011-07-23T21:57:36+00:00

Saves text by removing nearly duplicated text format strings by
creating ata__printk functions and printf extension %pV.

ata defconfig size shrinks ~5% (~8KB), allyesconfig ~2.5% (~13KB)

Format string duplication comes from:

 #define ata_link_printk(link, lv, fmt, args...) do { \
       if (sata_pmp_attached((link)->ap) || (link)->ap->slave_link)    \
               printk("%sata%u.%02u: "fmt, lv, (link)->ap->print_id,   \
                      (link)->pmp , ##args); \
       else \
               printk("%sata%u: "fmt, lv, (link)->ap->print_id , ##args); \
       } while(0)

Coalesce long formats.
