Hi Sean
Why do you need this global variable? What if somebody has two
switches connected?

It is better to move the functions around than have forward
declarations.

So here you would pass priv to _mt7530_read().

This is where your need for lpriv comes, you can only pass a single
argument. But you can work around it. readx_poll_timeout is a
#define. So there is no type check for _mt7530_read, or the arg passed
to it. So pass a struct containing the address and priv.
I think you can then kill of your global lpriv.
