Marc Ferland dbce1e4c4f dmaengine: xilinx_dma: use readl_poll_timeout_atomic variant ... [ Upstream commit 0ba2df09f1500d3f27398a3382b86d39c3e6abe2 ] The xilinx_dma_poll_timeout macro is sometimes called while holding a spinlock (see xilinx_dma_issue_pending() for an example) this means we shouldn't sleep when polling the dma channel registers. To address it in xilinx poll timeout macro use readl_poll_timeout_atomic instead of readl_poll_timeout variant.
