backlight brightness

[MrAndini]

Is it possible to add ability to change backlight brightness on the NDS to the arm7 common lib?

This is handy if you want to reduce the power consumption on the DS for an application.

I can do in my own code,
writePowerManagement(PM_DSLITE_REG, 2);
but can see where you are heading with the arm7 code and would like to avoid having my code crash on future devkitpro updates.
