From 0f909361062d42b0ff7c6522e2347b56a0bf43cc Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 7 May 2012 12:31:18 +0200 Subject: [PATCH] NFC: Remove unneeded pn533 dev NULL check container_of() works by subtracting the offset of the member. The math can't really return a zero here. Sometimes people check it when they actually meant to check something else but in this case we can just remove the check.
