Date: Sun, 28 Jun 2015 18:22:24 +0200 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Alex Williamson <alex.williamson@...hat.com>, kvm@...r.kernel.org CC: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Alexey Kardashevskiy <aik@...abs.ru>, Julia Lawall <julia.lawall@...6.fr>, Michael Ellerman <mpe@...erman.id.au> Subject: [PATCH 1/2] vfio: powerpc/spapr: Delete an unnecessary check before the function call "kfree" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Sun, 28 Jun 2015 17:43:48 +0200 The kfree() 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.
