[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.
