miscdev name field is just a char pointer and I need an static array to man=
ipulate the name with index

>=20

It is not parent and mfd field is the parent

>=20
> What operations?
>=20

The MFD driver will create 2 devices, one is for phc driver and another one=
 is this driver.
The lock is to make sure these 2 driver's operations are synchronized.=20

>=20
> Index into what?
>=20

index is passed by mfd driver and will be used as part of device name such =
as "rsmu0"
