Randy Dunlap 0ba4887c63 regulator: fix kernel-doc warnings
Fix kernel-doc warnings in regulator/driver.h:

Warning(linux-next-20090108//include/linux/regulator/driver.h:95): Excess struct/union/enum/typedef member 'set_current' description in 'regulator_ops'
Warning(linux-next-20090108//include/linux/regulator/driver.h:95): Excess struct/union/enum/typedef member 'get_current' description in 'regulator_ops'
Warning(linux-next-20090108//include/linux/regulator/driver.h:124): No description found for parameter 'irq'

* struct regulator_ops - regulator operations.
*
* This struct describes regulator operations which can be implemented by
* regulator chip drivers.
*
* @enable: Enable the regulator.
* @disable: Disable the regulator.
* @is_enabled: Return 1 if the regulator is enabled, 0 otherwise.
*
* @set_voltage: Set the voltage for the regulator within the range specified.
* The driver should select the voltage closest to min_uV.
* @get_voltage: Return the currently configured voltage for the regulator.
*
* @set_current_limit: Configure a limit for a current-limited regulator.
* @get_current_limit: Get the limit for a current-limited regulator.
*
* @set_mode: Set the operating mode for the regulator.
* @get_mode: Get the current operating mode for the regulator.
* @get_optimum_mode: Get the most efficient operating mode for the regulator
* when running with the specified parameters.
*
* @set_suspend_voltage: Set the voltage for the regulator when the system
* is suspended.
* @set_suspend_enable: Mark the regulator as enabled when the system is
* suspended.
* @set_suspend_disable: Mark the regulator as disabled when the system is
* suspended.
* @set_suspend_mode: Set the operating mode for the regulator when the
* system is suspended.
