[PATCH 21/39] ALSA: riptide: Fix the missing snd_card_free() call at probe error

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
