From 79e40b06a4ebfc8e0a48ed6164345f8e0a96b699 Mon Sep 17 00:00:00 2001 From: Amelie Delaunay Date: Mon, 11 Oct 2021 11:42:57 +0200 Subject: [PATCH] dmaengine: stm32-dma: mark pending descriptor complete in terminate_all To prevent accidental repeated completion, mark pending descriptor complete in terminate_all. It can be the case when terminate_all is called while no end of transfer interrupt occurs.
