Subject: [PATCH 14/14] xhci: Move xhci MSI sync function to to xhci-pci
Date: Fri, 17 Mar 2023 17:47:15 +0200	[thread overview]
Message-ID: <20230317154715.535523-15-mathias.nyman@linux.intel.com> (raw)
In-Reply-To: <20230317154715.535523-1-mathias.nyman@linux.intel.com>

From: Josue David Hernandez Gutierrez <josue.d.hernandez.gutierrez@intel.com>

Move function to sync MSI from xhci.c to xhci-pci.c to decouple PCI
specific code from generic xhci code.

No functional changes, function is an exact copy
