This patch removes the null test on dvb. dvb is initialized at the
beginning of the function to &port->dvb. Since port is dereferenced
prior to the null test, port must be a valid pointer, and
&port->dvb cannot be null.
The following Coccinelle script is used for detecting the change:
@r@
expression e,f;
identifier g,y;
statement S1,S2;
@@
*e = &f->g
<+...
f->y
...+>
*if (e != NULL || ...)
S1 else S2
