Subject: [PATCH 1/1] ARM-kernel: Deletion of unnecessary checks before two function calls

The functions smp_set_ops() and unwind_table_del() test whether their argument
is NULL and then return immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
