From 7d0771970c51e736758525dd71fb82dd036b823a Mon Sep 17 00:00:00 2001 From: David Brownell Date: Wed, 17 Jun 2009 16:26:03 -0700 Subject: spi: move common spi_setup() functionality into core Start moving some spi_setup() functionality into the SPI core from the various spi_master controller drivers: - Make that function stop being an inline; - Move two common idioms from drivers into that new function: * Default bits_per_word to 8 if that field isn't set * Issue a standardized dev_dbg() message This is a net minor source code shrink, and supports enhancments found in some follow-up patches.
