From 7456fe486a31308c79efa891c1be795715bf0070 Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Thu, 3 Sep 2020 13:25:38 +0200 Subject: usb/host: ehci-platform: Use pm_ptr() macro Use the newly introduced pm_ptr() macro, and mark the suspend/resume functions __maybe_unused. These functions can then be moved outside the CONFIG_PM_SUSPEND block, and the compiler can then process them and detect build failures independently of the config. If unused, they will simply be discarded by the compiler.
