mfd: menelaus: Remove null pointer dereference
If vtg is NULL, it is not possible to access its mode_reg field. At all
sites where the static function menelaus_set_voltage is called, the first
argument is the address of a structure defined in the file. So, the null
test is unnecessary and is removed. Also, a label is done away with.
This problem was found using the following Coccinelle semantic match:
// <smpl>
@@
expression E, E1;
identifier f;
statement S1,S2,S3;
@@
* if (E == NULL)
{
... when != if (E == NULL) S1 else S2
when != E = E1
* E->f
... when any
return ...;
}
else S3
// </smpl>
