PM / devfreq: constify attribute_group structures.

2017-07-06T01:17:24+00:00

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by  work with const
attribute_group. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
    621	    176	      0	    797	    31d	drivers/devfreq/governor_userspace.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   670	    144	      0	    814	    32e	drivers/devfreq/governor_userspace.o

PM / devfreq: tegra: fix error return code in tegra_devfreq_probe()

2017-07-06T01:16:17+00:00

platform_get_irq() returns an error code, but the tegra-devfreq
driver ignores it and always returns -ENODEV. This is not correct,
and prevents -EPROBE_DEFER from being propagated properly.

Notice that platform_get_irq() no longer returns 0 on error:

Print and propagate the return value of platform_get_irq on failure.

PM / devfreq: exynos-ppmu: Staticize event list

2017-06-12T01:12:07+00:00

The ppmu_events array is accessed only in this compilation unit so it
can be made static.

PM / devfreq: Move struct devfreq_governor to devfreq directory

2017-04-12T03:42:14+00:00

This patch moves the struct devfreq_governor from header file
to the devfreq directory because this structure is private data
and it have to be only accessed by the devfreq core.

scripts/spelling.txt: add "followings" pattern and fix typo instances

2017-02-28T02:43:47+00:00

Fix typos and add the following to the scripts/spelling.txt:

  followings||following

While we are here, add a missing colon in the boilerplate in DT binding
documents.  The "you SoC" in allwinner,sunxi-pinctrl.txt was fixed as
well.

I reworded "as the followings:" to "as follows:" for
drivers/usb/gadget/udc/renesas_usb3.c.

PM / devfreq: Modify the device name as devfreq(X) for sysfs

2017-01-31T07:57:19+00:00

This patch modifies the device name as devfreq(X) for sysfs by using the 'devfreq'
prefix word instead of separate device name. On user-space aspect, user would
find the some devfreq drvier with 'devfreq(X)' pattern. So, this patch modify the
device name as following:
- /sys/class/devfreq/[non-standard device name] -> /sys/class/devfreq/devfreq(X)
