From 547c9af67b4edb6193bf03fa766de3fa14a55629 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 12 Apr 2022 12:26:14 +0200 Subject: [PATCH] ALSA: ice1724: Fix the missing snd_card_free() call at probe error commit 4a850a0079ce601c0c4016f4edb7d618e811ed7d 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() on the error from the probe callback using a new helper function.
