From 28ccf02caa199e02a6fbf605496bfb9ee73f872c Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Fri, 8 Mar 2024 16:00:33 -0500 Subject: [PATCH] dma: xilinx_dpdma: Remove unnecessary use of irqsave/restore xilinx_dpdma_chan_done_irq and xilinx_dpdma_chan_vsync_irq are always called with IRQs disabled from xilinx_dpdma_irq_handler. Therefore we don't need to save/restore the IRQ flags.
