Subject: [PATCH 1/7] drivers/staging: Remove double test

The 1 element of the array is tested twice.  Change the code so that the
remaining 3 element of the array is tested instead of testing the 1 element
a second time.

The sematic match that finds this problem is as follows:

// <smpl>
@expression@
expression E;

(
* E
  || ... || E
|
* E
  && ... && E
)
// </smpl>

This is just as guess as to what the correct code should be.
