From 119fc8c9acde650fb92b44c34ea6fc84feb0f6dd Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Fri, 21 Mar 2008 22:55:45 +0100 Subject: [PATCH] USB: test for NULL return from platform_get_resource() in ohci_hcd_sm501_drv_remove() platform_get_resource() may return null, so although it seems it will never do so here unless there's a bug elsewhere, it does no harm to be defensive and test.
