Commit 4dbd8f63f07a (regulator: gpio-regulator: Set the smallest voltage/current in the specified range) forgot to set the newly introduced best_val. Therefore it stayed always at INT_MAX thus breaking the setting of the voltage. Included is also an init value for target, as warnings about a possibly uninitialised target started appearing with this fix.

2012-06-04regulator: palmas: Fix wrong kfree callsAxel Lin1-7/+0
The devm_kzalloc function eliminates the need for manual resource releasing and simplify error handling. Resources allocated by devm_* are freed automatically on driver detach. Thus adding kfree calls here will introduce double free bug. The memory of desc array and the pointers to the rdev[] are allocated by devm_kzalloc call for struct palmas_pmic. struct palmas_pmic { struct palmas *palmas; struct device *dev; struct regulator_desc desc[PALMAS_NUM_REGS]; struct regulator_dev *rdev[PALMAS_NUM_REGS]; struct mutex mutex; int smps123; int smps457; int range[PALMAS_REG_SMPS10]; }; Which means we should not call kfree for pmic->rdev and pmic->desc.

2012-05-20mfd: Convert wm831x to irq_domainMark Brown3-15/+23
The modern idiom is to use irq_domain to allocate interrupts. This is useful partly to allow further infrastructure to be based on the domains and partly because it makes it much easier to allocate virtual interrupts to devices as we don't need to allocate a contiguous range of interrupt numbers. Convert the wm831x driver over to this infrastructure, using a legacy IRQ mapping if an irq_base is specified in platform data and otherwise using a linear mapping, always registering the interrupts even if they won't ever be used. Only boards which need to use the GPIOs as interrupts should need to use an irq_base. This means that we can't use the MFD irq_base management since the unless we're using an explicit irq_base from platform data we can't rely on a linear mapping of interrupts. Instead we need to map things via the irq_domain - provide a conveniencem function wm831x_irq() to save a small amount of typing when doing so. Looking at this I couldn't clearly see anything the MFD core could do to make this nicer. Since we're not supporting device tree yet there's no meaningful advantage if we don't do this conversion in one, the fact that the interrupt resources are used for repeated IP blocks makes accessor functions for the irq_domain more trouble to do than they're worth.
