When mfp.o is disabled like this, I get a link error in two drivers
using the exported interface:
ERROR: "mfp_set_groupg" [drivers/spi/spi-nuc900.ko] undefined!
ERROR: "mfp_set_groupi" [drivers/input/keyboard/w90p910_keypad.ko]
undefined!
Why remove mfp modules? this multifunction pin driver should be used for
those two drivers, if no mfp_set_groupX, I don't think driver can work.
Now mfp has standard driver subsystem?
Any idea for a better migration strategy?
Arnd, If you still think the mfp should be removed, we can send a series
patches to instead of using mfp interface quickly, and do mfp set in
local driver. Do you think it is ok?
