Axel Lin 0f69c897f3 regulator: max8649 - fix setting extclk_freq
The SYNC bits are BIT6 and BIT7 of MAX8649_SYNC register.
pdata->extclk_freq could be [0|1|2].
(MAX8649_EXTCLK_26MHZ|MAX8649_EXTCLK_13MHZ|MAX8649_EXTCLK_19MHZ)
It requires to left shift 6 bits to properly set extclk_freq.

Wolfram Sang 59bfee6e06 i2c: Remove obsolete cleanup for clientdata
A few new i2c-drivers came into the kernel which clear the clientdata-pointer
on exit. This is obsolete meanwhile, so fix it and hope the word will spread.

Axel Lin 8ecee36adc regulator: wm8350-regulator - fix the logic of checking REGULATOR_MODE_STANDBY mode
In wm8350_dcdc_set_mode(), we set DCx_SLEEP bit of WM8350_DCDC_SLEEP_OPTIONS
register for REGULATOR_MODE_STANDBY mode.
( DCx_SLEEP bits: 0: Normal DC-DC operation 1: Select LDO mode )

In wm8350_dcdc_get_mode(), current logic to determinate
REGULATOR_MODE_STANDBY mode is just reverse.
( sleep is set should mean REGULATOR_MODE_STANDBY mode. )

Axel Lin e260999c66 regulator: wm831x-ldo - fix the logic to set REGULATOR_MODE_IDLE and REGULATOR_MODE_STANDBY modes
Problem description in current implementation:
When setting REGULATOR_MODE_IDLE mode, current implementation set
WM831X_LDO1_LP_MODE bit of ctrl_reg (which is wrong, it should clear the bit).
But due to a missing break statement for case REGULATOR_MODE_IDLE, the code
fall through to case REGULATOR_MODE_STANDBY and then clear
WM831X_LDO1_LP_MODE bit. So it still looks OK when checking the status
by wm831x_gp_ldo_get_mode().

When setting REGULATOR_MODE_STANDBY mode, it just does not work.
wm831x_gp_ldo_get_mode() will still return REGULATOR_MODE_IDLE because
the accordingly WM831X_LDO1_LP_MODE bit is clear.

Correct behavior should be:
Clear WM831X_LDO1_LP_MODE bit of ctrl_reg for REGULATOR_MODE_IDLE mode.
Set WM831X_LDO1_LP_MODE bit of ctrl_reg for REGULATOR_MODE_STANDBY mode.

Axel Lin d06563cb86 regulator: 88pm8607 - fix value range checking for accessing info->vol_table
In choose_voltage(), we use i as array index of info->vol_table.
The valid value range for i should be 0 .. ARRAY_SIZE(info->vol_table) - 1.

Take LDO1 as example, ARRAY_SIZE(LDO1_table) is 4, vol_nbits of LDO1 is 2.
for (i = 0; i < (2 << info->vol_nbits); i++)  is equivalent to
for (i = 0; i < 8; i++)
which is wrong.

The same value range checking also applies for index in pm8607_list_voltage().

regulator_register() still return success if max8998->dev is NULL,
