[linux-yocto] [yocto-4.12][PATCH 32/36] ALSA: hda - Fix unbalance of i915 module refcount

[Liwei Song]

From: Takashi Iwai <tiwai at suse.de>

commit fc18282cdcba984ab89c74d7e844c10114ae0795 upstream.

The commit dba9b7b6ca1a ("ALSA: hda - Fix doubly initialization of
i915 component") contained a typo that leads to the unbalance of i915
module reference.  The value to be checked is not chip->driver_type
but chip->driver_caps.

Fixes: dba9b7b6ca1a ("ALSA: hda - Fix doubly initialization of i915 component")
