From d712eaf29d3fe5928d891a4a90ac58644ad595ed Mon Sep 17 00:00:00 2001

Subject: ALSA: core: Deletion of unnecessary checks before two function calls

The functions snd_seq_oss_timer_delete() and vunmap() perform also input
parameter validation. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
