From 95d658002401e2e47a5404298ebe9508846e8a39 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Fri, 11 May 2012 11:42:40 -0300 Subject: [PATCH] msi: Invoke msi/msix_write_config from PCI core Also this functions is better invoked by the core than by each and every device. This allows to drop the config_write callbacks from ich and intel-hda. CC: Alexander Graf CC: Gerd Hoffmann CC: Isaku Yamahata Signed-off-by: Jan Kiszka Signed-off-by: Michael S.
