There is a name collision between 'struct platform_driver anatop_regulator' and 'struct anatop_regulator', which causes some section mismatch warnings like below. WARNING: vmlinux.o(.data+0x154d4): Section mismatch in reference from the variable anatop_regulator to the function .devinit.text:anatop_regulator_probe() The variable anatop_regulator references the function __devinit anatop_regulator_probe() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console Rename 'struct platform_driver anatop_regulator' to 'struct platform_driver anatop_regulator_driver' to fix the warnings.

2012-03-11regulator: Rename s5m8767_convert_voltage to s5m8767_convert_voltage_to_selAxel Lin1-12/+10
This function finds the smallest voltage that falls within the specified range, and then returns the selector. This rename makes the intention more clear. Also remove unneeded local variables min_vol and max_vol in s5m8767_set_voltage and s5m8767_set_voltage_buck.

2012-03-11regulator: Fix s5m8767_set_voltage_time_sel calculation valueSangbeom Kim1-1/+1
In the s5m8767_set_voltage_time_sel function, divisor unit is wrong. ramp_delay is usec unit. So 1000 should be multiplied. Signed-off-by: Sangbeom Kim <sbkim73@samsung.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
