  [PATCH 10/38] drbd: Deletion of an unnecessary check before the function call "lc_destroy" Philipp Reisner <philipp.reisner@linbit.com> - 2015-11-25 12:10 +0100

#1277226 — [PATCH 10/38] drbd: Deletion of an unnecessary check before the function call "lc_destroy"

From: Markus Elfring <elfring@users.sourceforge.net>

The lc_destroy() 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.
