From 872e5fa0781f926a78c729d682cd0c3a51acf175 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 12 Apr 2022 12:26:00 +0200 Subject: ALSA: ad1889: Fix the missing snd_card_free() call at probe error [ Upstream commit a8e84a5da18e6d786540aa4ceb6f969d5f1a441d ] 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() on the error from the probe callback using a new helper function.
