[PATCH] backlight/platform_lcd: change set power function parameter in plat_lcd_data

[Donghwa Lee]

In drivers/video/backlight/platform_lcd.c driver, to use lcd power
control function in platdata, it is used
set_power(struct plat_lcd_data *, unsigned int power) callback function.
set_power() function is consists of two parameters,
(struct plat_lcd_data *, unsigned int power).

But actually, there is no one to use (struct plat_lcd_data *), only use
second (unsigned int power) value to control lcd power on/off.

I don't know why (struct plat_lcd_data*) parameter is used in set_power()
callback function. Maybe I think it is unessesntial or changeable to another
meaningful variable. For example, struct lcd_device *, it can be used to
control regulator_get() function.

In mach-nuri.c, it has been patching by Minku Kang, (struct lcd_device*) can be
used to regulator lcd power on/off, and many other machines uses regulator
control to on/off lcd power.

So I think more meaningful variable that (struct lcd_device* ) can be
substituted for unessential variable that (struct plat_lcd_data *).

Thank you,
Donghwa Lee
