Thanks for your feedback.
Does this example show a conflict between long comments like "snd_emu10k1_ctl_private_free( ... *kctl)" after patch ranges and line length limitation for email eventually?

I have attached my update suggestion with a slightly different commit title as before. Is this variant acceptable?
Regards, Markus From 23bb7bd1325b7c9cc81761db3ebf3ea19f85338d Mon Sep 17 00:00:00 2001 From: Markus Elfring <elfring@users.sourceforge.net> Date: Mon, 3 Nov 2014 14:54:36 +0100 Subject: [PATCH] ALSA: emu10k1: Deletion of unnecessary checks before three function calls
The functions kfree(), release_firmware() and snd_util_memhdr_free() test whether their argument is NULL and then return immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
