From b840bc11b5062803c204d8a9625a1a1c5812d6d6 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Mon, 11 Jan 2010 15:05:35 +0100 Subject: [PATCH] mtd: mxc-nand: no need to check for validity of platform driver data MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The probe function calls platform_set_drvdata with a valid pointer when the probe is successful. As mxcnd_suspend and mxcnd_resume are only called on bound devices, platform_get_drvdata always returns non-NULL. This fix isn't critical as the pointer is always valid so it doesn't matter if the compiler generated code for it or not.
