From mboxrd@z Thu Jan 1 00:00:00 1970 From: Heiner Kallweit Subject: [PATCH 1/4] spi: fsl-espi: simplify fsl_espi_setup_transfer Date: Tue, 13 Sep 2016 23:15:45 +0200 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Cc: "linux-spi-u79uwXL29TY76Z2rM5mHXA@public.gmane.org" To: Mark Brown Return-path: Sender: linux-spi-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-ID: If t is not null then the SPI core takes care that bits_per_word and speed_hz are populated. This allows to simplify fsl_espi_setup_transfer.
