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.

Your patch can't be applied cleanly due to your MUA breaking the lines. Please fix your MUA setup, or use an attachment if it's impossible, and resend the patch.
Also, try to align the subject line with the relevant commits. See "git log sound/pci/emu10k1"
thanks,
Takashi
