[SOLVED] Tethering iphone : kernel modules

Hi,

I have observed that when I plug in my iphone,
the ipheth module and apple_mfi_fastcharge load well

but if I unplug / replug, the phone does not charge and tethering is not functional
except if I load the apple_mfi_fastcharge module manually before

I don't observe this problem with my own kernel, because the apple_mfi_fastcharge module is compiled built-in

First, does anyone notice the same thing ?
And, it could be from something else, but in case, would it be possible to CC this module built-in ?

Code:-CONFIG_APPLE_MFI_FASTCHARGE=m
+CONFIG_APPLE_MFI_FASTCHARGE=y
