Julia Lawall 00185a60c3 USB: Remove redundant test in pxa27x_udc and ftdi_sio 
priv is checked not to be NULL near the beginning of the function and not
changed subsequently, making the test redundant.

A simplified version of the semantic patch that makes this change is as
follows: (http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@r exists@
local idexpression x;
expression E;
position p1,p2;
@@

if (x@p1 == NULL || ...) { ... when forall
   return ...; }
... when != \(x=E\|x--\|x++\|--x\|++x\|x-=E\|x+=E\|x|=E\|x&=E\|&x\)
(
x@p2 == NULL
|
x@p2 != NULL
)

// another path to the test that is not through p1?

local idexpression r.x;
position r.p1,r.p2;
