This patch fix the error handle of function cci_pmu_probe():
- using IS_ERR() instead of NULL test for the return value of
devm_ioremap_resource() since it nerver return NULL.
- remove kfree() for devm_kzalloc allocated memory
- remove dev_warn() since devm_ioremap_resource()

Hi Rafael/Daniel,
This is a small cleanup patchset for CPUIdle which can go in 3.13 if it looks
okay to you guys..
Mostly trivial patches but few are doing good/significant changes. Tested on my
thinkpad with suspend/resume and didn't found any broken stuff with it.
I a not very sure about this
When I first read cpuidle_replace_governor()'s name I thought it will replace
the governor (as per its name) but then found that it just returns the next best
governor. And cpuidle_unregister_governor() actually replaces it.
We always replace current governor with the next best and this
Currently we have multiple definitions of few routines based on following config
option: CONFIG_CPU_IDLE_MULTIPLE_DRIVERS.
These are present to save space by not creating per-cpu variable for platforms
which need only one cpuidle driver to be registered for all CPUs.
But this setup has a
In cpuidle_coupled_register_device() we do following:
if (WARN_ON(!cpumask_equal(>coupled_cpus, >coupled_cpus)))
coupled->prevent++;
This is only required to be done when we are using 'coupled' from an existing
cpuidle_device and not when we have just done this:
Loop for states is currently present on callers side and so is replicated at
several places. It would be better to move that inside cpuidle_free_state_kobj()
instead.
This patch does it.

We always need to allocate struct cpuidle_device_kobj for all CPUs and so there
is no real need to have a pointer to it inside struct cpuidle_device.

There was a trailing whitespace. I fixed it here, and pulled it in my
tree for -next.
On systems where certain filesystem contents cannot be entirely trusted,
it is beneficial to block mounts on symlinks. This makes sure that
malicious filesystem contents cannot trigger the over-mounting of trusted
filesystems. (For example, a bind-mounted subdirectory of /var cannot be

This patch series is the new s5pv210 clock implementation
(using common clk framework).
This implementation is compatible with device tree definition and board
files.
This patch series is based on linux-next and has been tested on goni and
aquila
boards using board file.
