From 8576f815d5c8beb8b10f96abe31831b90af3d352 Mon Sep 17 00:00:00 2001 From: Rafał Miłecki Date: Wed, 11 May 2011 02:10:58 +0200 Subject: ssb: move ssb_commit_settings and export it MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commiting settings is possible on devices without PCI core (but with CC core). Export it for usage in drivers supporting other cores. Signed-off-by: Rafał Miłecki Signed-off-by: John W.
