From 30af9b558a56200bda5febd140d5b826581d1f15 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 9 Aug 2013 17:26:37 +0100 Subject: spi/bitbang: Drop empty setup() functions Now that the bitbang core does not require a setup() function we can drop the check in the altera, nuc900 and xilinx drivers.
