Indeed.

Ha so for some (all ?) of them, another include is providing the leds.h,
interesting. For many of them it is either :
 - linux/power_supply.h
 - linux/gpio_charger.h
 - an mfd device (such as mfd/htc-pasic3.h)
 - etc ...

Yeah as you wish, after all you're removing the leds.h and you'r patch addresses
that, it's beyond its scope to fix all pxa boards which don't include leds.h
properly.

Cheers.
