[PATCH] dmaengine: at_xdmac: don't restore unsaved status
From: Alexandre Belloni <hidden>
Date: 2016-12-01 10:49:11
save_gs is supposed to save the channel status in order to be restored at resume time but it is never updated and is always 0. Anyway, the channel status is updated in the per channel loop later in the resume function.
