From 8d9d2a4b6ca0013b62a438808d22bdd615abcd00 Mon Sep 17 00:00:00 2001 From: Scott Jiang Date: Mon, 23 Apr 2012 18:18:11 -0400 Subject: [PATCH] spi/spi_bfin_sport: drop bits_per_word from client data Since the member was dropped from the common Blackfin header, we need to stop using it in the SPORT driver too.
