From 22db089a4437a72277677f99717af499560b13f2 Mon Sep 17 00:00:00 2001 From: "Ahmed S. Darwish" Date: Fri, 11 Nov 2022 14:54:33 +0100 Subject: genirq/msi: Add bus token to struct msi_domain_info Add a bus token member to struct msi_domain_info and let msi_create_irq_domain() set the bus token. That allows to remove the bus token updates at the call sites. Suggested-by: Thomas Gleixner Signed-off-by: Ahmed S.
