I'm seeing a few build failures with Linux 6.3.4-rc1 (20efcce0526d) due to the drivers/usb/host/xhci.c driver:

drivers/usb/host/xhci.c:497:19: error: static declaration of 'xhci_try_enable_msi' follows non-static declaration
  497 | static inline int xhci_try_enable_msi(struct usb_hcd *hcd)
      |                   ^~~~~~~~~~~~~~~~~~~
In file included from drivers/usb/host/xhci.c:22:
drivers/usb/host/xhci.h:2146:5: note: previous declaration of 'xhci_try_enable_msi' was here
 2146 | int xhci_try_enable_msi(struct usb_hcd *hcd);
      |     ^~~~~~~~~~~~~~~~~~~

Example build failure: https://gitlab.com/cip-project/cip-testing/linux-stable-rc-ci/-/jobs/4328533790#L2178
Pipeline: https://gitlab.com/cip-project/cip-testing/linux-stable-rc-ci/-/pipelines/875108293

Commit 78887e3e5f00 ("xhci: Avoid PCI MSI/MSIX interrupt reinitialization at resume") adds the offending code.
I'm only seeing this for the 6.3 rc.

Kind regards, Chris
