Date: Mon, 26 Oct 2015 22:28:25 +0100 From: Julia Lawall <Julia.Lawall@...6.fr> To: Julia Lawall <Julia.Lawall@...6.fr> Cc: kernel-janitors@...r.kernel.org, Gilles Muller <Gilles.Muller@...6.fr>, Nicolas Palix <nicolas.palix@...g.fr>, Michal Marek <mmarek@...e.com>, cocci@...teme.lip6.fr, linux-kernel@...r.kernel.org, Fabian Frederick <fabf@...net.be> Subject: [PATCH 1/2 v2] coccinelle: ifnullfree: various cleanups Adjust tests to compare against NULL, to match cases that explicitly make that comparison. Remove removal and re-addition of freeing functions. Add position variable on usb_free_urb in the non-patch case.
