-Subject: Partial revert of xhci: use pm_ptr() instead #ifdef for CONFIG_PM conditionals
-To: Greg Kroah-Hartman <gregkh@linuxfoundation.org>, stable@vger.kernel.org

-Message-ID: <20250118122409.4052121-1-re@w6rz.net>
-
-commit 9734fd7a2777 ("xhci: use pm_ptr() instead of #ifdef for CONFIG_PM
-conditionals") did not quite work properly in the 6.1.y branch where it was
-applied to fix a build error when CONFIG_PM was set as it left the following
-build errors still present:
-
- ERROR: modpost: "xhci_suspend" [drivers/usb/host/xhci-pci.ko] undefined!
- ERROR: modpost: "xhci_resume" [drivers/usb/host/xhci-pci.ko] undefined!
-
-Fix this up by properly placing the #ifdef CONFIG_PM in the xhci-pci.c and
-hcd.h files to handle this correctly.

-[ Trimmed the partial revert down to an even smaller bit to only be what
- is required to fix the build error - gregkh]
