From cb50f3f32a044ea45192a43e756b26048d35ba95 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 25 Feb 2022 19:23:47 +0200 Subject: [PATCH] spi: pxa2xx-pci: Drop unneeded checks in lpss_spi_setup() All of the LPSS devices are using DMA and set the parameters up, hence no need to test for that.
