From c819a1b0907257d73de96af33d557668a5c0c895 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Mon, 1 Jul 2013 14:26:57 +0200 Subject: [PATCH 071/203] PCI: remove ARCH_SUPPORTS_MSI kconfig option Now that we have weak versions for each of the PCI MSI architecture functions, we can actually build the MSI support for all platforms, regardless of whether they provide or not architecture-specific versions of those functions. For this reason, the ARCH_SUPPORTS_MSI hidden kconfig boolean becomes useless, and this patch gets rid of it.
