From f006a4bcf8bb7096ec37356b09112a1f6bd68393 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 12 Apr 2022 12:26:32 +0200 Subject: ALSA: hdsp: Fix the missing snd_card_free() call at probe error commit e2263f0bf7443a200a5c1c418baefd92f1674600 upstream. The previous cleanup with devres may lead to the incorrect release orders at the probe error handling due to the devres's nature. Until we register the card, snd_card_free() has to be called at first for releasing the stuff properly when the driver tries to manage and release the stuff via card->private_free(). This patch fixes it by calling snd_card_free() manually on the error from the probe callback.
