2015-10-30mfd: lm3533: Fix unused variable build warningSudip Mukherjee1-1/+0
We were getting build warning about unused variable 'ret'. The commit c749db571dcf has removed the use of ret but missed removing the variable which is unused now.

2015-10-30mfd: lm3533: Simplify function return logicJavier Martinez Canillas1-10/+2
The invoked functions already return zero on success or a negative errno code so there is no need to open code the logic in the caller. Signed-off-by: Javier Martinez Canillas <[email protected]> Signed-off-by: Lee Jones <[email protected]>
2015-08-11mfd: Drop owner assignment from i2c_driversKrzysztof Kozlowski1-1/+0
i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <[email protected]> Signed-off-by: Lee Jones <[email protected]>
2015-01-22mfd: lm3533: Constify struct regmap_configKrzysztof Kozlowski1-1/+1
The regmap_config struct may be const because it is not modified by the driver and regmap_init() accepts pointer to const. Signed-off-by: Krzysztof Kozlowski <[email protected]> Signed-off-by: Lee Jones <[email protected]>
2013-07-31mfd: Use dev_get_platdata()Jingoo Han1-4/+4
Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. Signed-off-by: Jingoo Han <[email protected]> Signed-off-by: Lee Jones <[email protected]>

2012-09-15mfd: core: Push irqdomain mapping out into devicesMark Brown1-3/+4
Currently the MFD core supports remapping MFD cell interrupts using an irqdomain but only if the MFD is being instantiated using device tree and only if the device tree bindings use the pattern of registering IPs in the device tree with compatible properties. This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver. Signed-off-by: Mark Brown <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2012-05-20mfd: Mark two lm3533 zone registers as volatileJohan Hovold1-1/+1
Mark the two currently unused zone registers as volatile in regmap for completeness. Signed-off-by: Johan Hovold <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2012-05-20mfd: Fix return type of lm533 attribute is_visibleJohan Hovold1-1/+1
Since commit 587a1f1659 ("switch ->is_visible() to returning umode_t") the return type of is_visible is umode_t rather than mode_t. This silences a compiler warning on some architectures where these types are not compatible.

2012-05-20mfd: Silence an lm3533 gcc warningDan Carpenter1-1/+1
This is supposed to be umode_t. It causes a GCC warning: drivers/mfd/lm3533-core.c:440:2: warning: initialization from incompatible pointer type [enabled by default] drivers/mfd/lm3533-core.c:440:2: warning: (near initialization for ‘lm3533_attribute_group.is_visible’) [enabled by default] Signed-off-by: Dan Carpenter <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
