2014-06-01i2c: rcar: refactor setting up msgWolfram Sang
Setting up a read or write message is similar enough to be done in one function. Also, move a helper function into the new function since it is only used here.

2014-06-01i2c: rcar: check bus free before first messageWolfram Sang
We should always check if the bus is free, independently if it is a read or write. It should be done before the first message, though. After that, we ourselves keep the bus busy. Remove a 'ret' assignment which only silenced a build warning.

2014-06-01ASoC: cache: Fix possible ZERO_SIZE_PTR pointer dereferencing error.Xiubo Li
Since we cannot make sure the 'reg_size' will always be none zero here, and then if 'reg_size' equals to zero, the kzalloc() will return ZERO_SIZE_PTR, which equals to ((void *)16).

2014-06-01regulator: core: Fix the init of DT defined fixed regulatorsAlban Bedel
When a regulator is defined using DT and it has a single voltage the regulator init always tries to apply this voltage. However it fails if the regulator isn't settable because it is using an internal low level function. To overcome this we now first query the regulator and only set it if needed.

2014-06-01regulator: core: Disable unused regulators after deferred probing is doneSaravana Kannan
regulator_init_complete does a scan of regulators which dont have always-on or consumers are automatically disabled as being unused. However, with deferred probing, late_initcall() is too soon to declare a regulator as unused as the regulator itself might not have registered due to defferal - Example: A regulator deffered due to i2bus not available which in turn is deffered due to pinctrl availability. Since deferred probing is done in late_initcall(), do the cleanup of unused regulators by regulator_init_complete in late_initcall_sync instead of late_initcall.

2014-06-01regulator: Don't disable unused regulators we don't have permission forMark Brown
In the spirit of conservatism that governs our general approach to permissions it is better if we don't touch regulators we weren't explicitly given permissions to control. This avoids the need to explicitly specify unknown regulators in DT as always on, if a regulator is not otherwise involved in software control it can be omitted from the DT. Regulators explicitly given constraints in DT still need to have an always on constraint specified as before. Signed-off-by: Mark Brown <broonie@linaro.org>
