Subject: [PATCH] iio: trigger: free trigger resource correctly
Date: Tue, 17 Jan 2017 19:00:28 -0800 [thread overview]
Message-ID: <20170118030016.GA23724@d830.WORKGROUP> (raw)
Using iio_trigger_put() to free a trigger leads to release of
a resource we never held. Replace with iio_trigger_free().
Signed-off-by: Alison Schofield <amsfield22@gmail.com>

Patches to use devm_* funcs are ready to follow this for
the interrupt & bfin-timer triggers.
