Change pcf_doAddress() function's type from int to void as it is always
returns 0. This way there is no need for extra assignment and extra checks
when the function is called.
Remove assignment of pcf_doAddress() and replace it with a simple function
call.

Hi Cezar,

thanks for taking care of this.

The "is" is not needed.

It's not that I care much myself, but normally when someone
suggests a change, you should recognize it with "Suggested-by".

Please insert this patch in the same series with your

"[PATCH v8 1/1] i2c: pcf8584: Move 'ret' ... "

patch.

while you are at this you can use the chance to rename this
function to a more kernel style naming. E.g.:

	pcf_send_address()

I would accept it in the same patch, but if you prefer you can
send it as a 3/3 patch. Your choice.

In any case, thanks for these cleanups!
