IB/ehca: Drop unnecessary NULL test
list_for_each_entry binds its first argument to a non-null value, and thus
any null test on the value of that argument is superfluous.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
iterator I;
expression x;
statement S,S1,S2;
@@
I(x,...) { <...
- if (x == NULL && ...) S
...> }
// </smpl>
