From 55d2d046b23b9bcb907f6b3e38e52113d55085eb Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 12 Apr 2022 12:26:19 +0200 Subject: [PATCH] ALSA: rme32: Fix the missing snd_card_free() call at probe error 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.
