Subject: [PATCH 09/11] PCI: Move pci_resource_alignment() to setup-res.c file
Date: Wed, 29 Apr 2026 15:26:15 +0300	[thread overview]
Message-ID: <20260429122617.7324-10-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20260429122617.7324-1-ilpo.jarvinen@linux.intel.com>

pci_resource_alignment() is a bit one the complex side to have in a
header so put it into setup-res.c.
