A call to one of those functions would require a valid wm97xx structure as
input to those functions.
How am i suppose to get a valid pointer to the structure which is required
by the function, if i am going to use it in a read function provided by the
file operations structure of the char driver?

Yes, i have read that. It says directly addressable but it's not like i can
access those addresses straight from user space. So how do i access them .
In the above case how do i access the register of the wm97 codec ic which
is on an AC97 bus?
@Anish
Yes, wm97xx-core is a touch driver fal

Can someone give me some pointers or tell me as to how can one use a
platform driver for reading and writing?
For example, if i have a wm97xx codec IC, a core platform driver is
provided (as on the below link).
