From 7aea2a7ddc2eb202e7963bd390d7b069f6e116dd Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Thu, 3 Sep 2020 13:25:42 +0200 Subject: [PATCH] usb/misc: usb4604: 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.
