Subject: [PATCH 1/2] phy: tegra: xusb: annotate PM functions as __maybe_unused
Date: Wed, 21 Apr 2021 15:56:07 +0200 [thread overview]
Message-ID: <20210421135613.3560777-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
Depending on the configuration, there are no references to these
two helpers:
drivers/phy/tegra/xusb.c:1286:12: error: 'tegra_xusb_padctl_resume_noirq' defined but not used [-Werror=unused-function]
1286 | static int tegra_xusb_padctl_resume_noirq(struct device *dev)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/phy/tegra/xusb.c:1276:12: error: 'tegra_xusb_padctl_suspend_noirq' defined but not used [-Werror=unused-function]
Mark them as __maybe_unused to shut up the warnings without adding
fragile #ifdefs.
Fixes: b8bb3d9c9b74 ("phy: tegra: xusb: Add sleepwalk and suspend/resume")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
