From: Dmitry Torokhov Date: Mon, 21 May 2007 04:17:44 +0000 (-0400) Subject: Input: aiptek - do not check for NULL in attribute methods X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=02fb6c385c72823af4fac83963a05be9163c73ea;p=linux-beck.git Input: aiptek - do not check for NULL in attribute methods It makes no sense to check for NULL in attribute methods - we do usb_set_intfdata before creating attributes and once attributes have been removed we are guaranteed to not be called.
