Subject: [PATCH 14/16] spi: pxa2xx: Remove two variables from struct chip_data
Date: Tue, 15 Sep 2015 16:26:26 +0300	[thread overview]
Message-ID: <1442323588-29642-14-git-send-email-jarkko.nikula@linux.intel.com> (raw)
In-Reply-To: <1442323588-29642-1-git-send-email-jarkko.nikula-VuQAYsv1563Yd54FQh9/CA@public.gmane.org>

There is no need to carry spi->max_speed_hz and spi->bits_per_word from
setup() in "struct chip_data" since pump_transfers() will anyway take the
transfer parameters from "struct spi_transfer". This is since SPI core
validates both bits_per_word and speed_hz transfer parameters and defaults
to spi->bits_per_word and spi->max_speed_hz in case these per transfer
parameters are not set.
