From 09417379be9b126e10ae7dcd7afc20b666146266 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Sat, 25 Jun 2005 14:58:49 -0700 Subject: [PATCH] remove redundant NULL checks before kfree() in sound/ and avoid casting pointers about to be kfree()'ed Checking a pointer for NULL before calling kfree() on it is redundant, kfree() deals with NULL pointers just fine. This patch removes such checks from sound/ This patch also makes another, but closely related, change. It avoids casting pointers about to be kfree()'ed.
