Subject: [PATCH v1 08/11] spi: pxa2xx-pci: Drop unneeded checks in lpss_spi_setup()
Date: Fri, 25 Feb 2022 19:23:47 +0200	[thread overview]
Message-ID: <20220225172350.69797-8-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20220225172350.69797-1-andriy.shevchenko@linux.intel.com>

All of the LPSS devices are using DMA and set the parameters up,
hence no need to test for that.
