2022-04-12ALSA: lx6464es: Fix the missing snd_card_free() call at probe errorTakashi Iwai
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. Fixes: 6f16c19b115e ("ALSA: lx6464es: Allocate resources with device-managed APIs") Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20220412102636.16000-34-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2021-07-19ALSA: lx6464es: Allocate resources with device-managed APIsTakashi Iwai
This patch converts the resource management in PCI lx6464es driver with devres as a clean up. Each manual resource management is converted with the corresponding devres helper, and the card object release is managed now via card->private_free instead of a lowlevel snd_device. This should give no user-visible functional changes. Link: https://lore.kernel.org/r/20210715075941.23332-42-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

lx_pipe_state() checks the return value from lx_message_send_atomic() and breaks the loop only when it's a negative value. However, lx_message_send_atomic() may return a positive error code (as the return code from the hardware), and then lx_pipe_state() tries to compare the uninitialized current_state variable.
