From 2b0ff43ae5ea8c21ee142cc5ae6b42aadfc3260b Mon Sep 17 00:00:00 2001 From: Laurentiu Tudor Date: Fri, 17 Nov 2017 15:38:26 +0200 Subject: staging: fsl-mc/dpio: remove incomplete refcount implementation There's an unfinished implementation of reference counting for dpaa2_io structure using atomics. Since it's unused lets remove it for now and, if needed at a later time, make use of krefs instead of rolling our own refcounting.
