--- Comment #19 from Marius Vlad <marius.c.vlad at intel.com> ---
My bad won't happen again. 

Tested with both patches (_init and _exit) and I see no warnings now:

commit 50bd9fb15ccf6f013131f334cd604d783c0c3186

    ALSA: hda - Fix yet another i915 pointer leftover in error path

    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.

commit f07183a706c41c8aabef9cd711e45a4ca367aeea

    ALSA: hda - Clear the leftover component assignment at snd_hdac_i915_exit()

    The commit [d745f5e7b8b2: ALSA: hda - Add the pin / port mapping on
    Intel ILK and VLV] introduced a WARN_ON() to check the pointer for
    avoiding the double initializations.  But hdac_acomp pointer wasn't
    cleared at snd_hdac_i915_exit(), thus after reloading the HD-audio
    driver, it may result in the false positive warning.  This patch makes
    sure to clear the leftover pointer at exit.
