ALSA: hda: Don't release card at firmware loading error
At the error path of the firmware loading error, the driver tries to release the card object and set NULL to drvdata. This may be referred badly at the possible PM action, as the driver itself is still bound and the PM callbacks read the card object. Instead, we continue the probing as if it were no option set. This is often a better choice than the forced abort, too. Fixes: 5cb543dba986 ("ALSA: hda - Deferred probing with request_firmware_nowait()") BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=207043 Link: https://lore.kernel.org/r/20200413082034.25166-2-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
