    Subject[PATCH 4.4 78/78] ALSA: hda - Fix yet another i915 pointer leftover in error path
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Takashi Iwai <tiwai@suse.de>

    commit 97cc2ed27e5a168cf423f67c3bc7c6cc41d12f82 upstream.

    The hdac_acomp object in hdac_i915.c is left as assigned even after
    binding with i915 actually fails, and this leads to the WARN_ON() at
    the next load of the module.
