ALSA: hda/tas2781: Fix acpi device refcount leak at tas2781_read_acpi()
The error path at tas2781_read_acpi() doesn't release the acpi_device
adev but releases another device physdev instead. This results in a
refcount leak. Fix it by replacing with the right object.
Fixes: 5be27f1e3ec9 ("ALSA: hda/tas2781: Add tas2781 HDA driver")
