From 85c2d1bb73dea16fd21b50742d79649e1c421692 Mon Sep 17 00:00:00 2001 From: Amelie Delaunay Date: Wed, 4 May 2022 17:53:21 +0200 Subject: [PATCH] dmaengine: stm32-mdma: fix chan initialization in stm32_mdma_irq_handler() [ Upstream commit da3b8ddb464bd49b6248d00ca888ad751c9e44fd ] The parameter to pass back to the handler function when irq has been requested is a struct stm32_mdma_device pointer, not a struct stm32_mdma_chan pointer. Even if chan is reinit later in the function, remove this wrong initialization.
