With gcc 4.1.2:
drivers/regulator/da9063-regulator.c: In function ‘da9063_regulator_probe’:
drivers/regulator/da9063-regulator.c:847: warning: ‘da9063_reg_matches’ is used
uninitialized in this function
If the parent device already has platform data, da9063_reg_matches will
not be initialized.

If CONFIG_OF=n:

drivers/regulator/da9063-regulator.c:712: warning: passing argument 1 of ‘PTR_ERR’ makes pointer from integer without a cast
drivers/regulator/da9063-regulator.c:712: warning: return makes pointer from integer without a cast
Use ERR_PTR() to encode an error code in a pointer.
PTR_ERR() is meant to decode an error code from a pointer.

da9063_ldo_lim_event() is only referenced in this driver, make it static.

regulator_register() does not return NULL, it returns ERR_PTR on error.

All the current limit tables have the values in ascend order.
So we can slightly optimize the for loop iteration because the first match
is the minimal value.

The driver adds support for the following DA9063 PMIC regulators:
- 11x LDOs (named LDO1 - LDO11),
- 6x buck converters (BCORE1, BCORE2, BPRO, BMEM, BIO, BPERI),
Regulators provide following operations:
- REGULATOR_CHANGE_STATUS and REGULATOR_CHANGE_VOLTAGE for all regulators,
- REGULATOR_CHANGE_MODE for LDOs and buck converters, where:
- LDOs allow REGULATOR_MODE_NORMAL and REGULATOR_MODE_STANDBY,
- buck converters allow REGULATOR_MODE_FAST, REGULATOR_MODE_NORMAL
and REGULATOR_MODE_STANDBY,
- REGULATOR_CHANGE_CURRENT for buck converters (current limits).
The driver generates REGULATOR_EVENT_OVER_CURRENT for LDO3, LDO4, LDO7, LDO8
and LDO11.
Internally, PMIC provides two voltage configurations for normal and suspend
system state for each regulator. The driver switches between those on
suspend/wake-up to provide quick and fluent output voltage change.
This driver requires MFD core driver for operation.
