Conflicts: drivers/devfreq/exynos4_bus.c Sync with Linus' tree to be able to apply patches that are against newer code (mvneta).

PM / devfreq: exynos4_bus: honor RCU lock usage

2013-01-22T12:28:40Z

OPP pointers cannot be expected to be valid beyond the boundary of rcu_read_lock and rcu_read_unlock. Unfortunately, the current exynos4 busfreq driver does not honor the usage constraint and stores the OPP pointer in struct busfreq_data. This could potentially become invalid later such as: across devfreq opp change decisions, resulting in unpredictable behavior. To fix this, we introduce a busfreq specific busfreq_opp_info structure which is used to handle OPP information. OPP information is de-referenced to voltage and frequency pairs as needed into busfreq_opp_info structure and used as needed. Signed-off-by: Nishanth Menon Signed-off-by: Rafael J. Wysocki

PM / devfreq: add locking documentation for recommended_opp

2013-01-22T12:28:39Z

OPP pointers are protected by RCU locks, the pointer validity is permissible only under the section of rcu_read_lock to rcu_read_unlock Add documentation to the effect. Signed-off-by: Nishanth Menon Signed-off-by: Rafael J. Wysocki

Drivers: misc: remove __dev* attributes.

2013-01-03T23:57:16Z

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, __devinitconst, 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 Signed-off-by: Greg Kroah-Hartman

Governors compiled as modules may use these functions. Signed-off-by: MyungJoo Ham Signed-off-by: Rafael J. Wysocki

PM / devfreq: Fix return value in devfreq_remove_governor()

PM / devfreq: Fix incorrect argument in error message

2012-11-26T10:17:48Z

'g' is cast to the error return code. Hence gives the following error which is fixed by this patch. drivers/devfreq/devfreq.c:645 devfreq_remove_governor() error: 'g' dereferencing possible ERR_PTR() Signed-off-by: Sachin Kamat Signed-off-by: MyungJoo Ham

PM / devfreq: missing rcu_read_lock() added for find_device_opp()

2012-11-26T10:17:46Z

opp_get_notifier() uses find_device_opp(), which requires to held rcu_read_lock. In order to keep the notifier-header valid, we have added rcu_read_lock(). Reported-by: Kees Cook Signed-off-by: MyungJoo Ham
