From: Axel Lin Date: Fri, 17 Jan 2014 10:53:40 +0000 (+0800) Subject: spi: Remove duplicate code to set default bits_per_word setting X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=23061f1eb844edd349c3a0f5f40e244c9d2abfde;p=openwrt%2Fstaging%2Fblogic.git spi: Remove duplicate code to set default bits_per_word setting The implementation in spi_setup() already set spi->bits_per_word = 8 when spi->bits_per_word is 0 before calling spi->master->setup. So we don't need to do it again in setup() callback.
