[PATCH] ALSA: emu10k1: Use common error handling code in snd_emu10k1_playback_open()

[Markus Elfring <Markus.Elfring@web.de>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Thu, 18 Jun 2026 12:24:36 +0200

Use an additional label so that a bit of exception handling can be better
reused at the end of this function implementation.

This issue was detected by using the Coccinelle software.
