    Subject[PATCH 2/2] ARM-kernel: Delete an unnecessary check before the function call "unwind_table_del"
    From: Markus Elfring <elfring@users.sourceforge.net>
    Date: Thu, 25 Jun 2015 15:05:21 +0200

    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.
