Subject: [PATCH 2/2] ARM-kernel: Delete an unnecessary check before the function call "unwind_table_del"

The unwind_table_del() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
