From abbd0ef1f2542621e0f94a7273b7f7e458a38497 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Sun, 18 Aug 2019 21:01:07 +0300 Subject: [PATCH] spi: spi-fsl-dspi: Reduce indentation in dspi_release_dma() There is no point in surrounding an entire function block in an if condition. Rather, exit early if the condition is false.
