Subject: [PATCH 4.4 23/41] spi: Fix tegra20 build with CONFIG_PM=n
Date: Mon,  4 Oct 2021 14:52:14 +0200	[thread overview]
Message-ID: <20211004125027.316190460@linuxfoundation.org> (raw)
In-Reply-To: <20211004125026.597501645@linuxfoundation.org>

From: Linus Torvalds <torvalds@linux-foundation.org>

[ Upstream commit efafec27c5658ed987e720130772f8933c685e87 ]

Without CONFIG_PM enabled, the SET_RUNTIME_PM_OPS() macro ends up being
empty, and the only use of tegra_slink_runtime_{resume,suspend} goes
away, resulting in

  drivers/spi/spi-tegra20-slink.c:1200:12: error: ‘tegra_slink_runtime_resume’ defined but not used [-Werror=unused-function]
   1200 | static int tegra_slink_runtime_resume(struct device *dev)
        |            ^~~~~~~~~~~~~~~~~~~~~~~~~~
  drivers/spi/spi-tegra20-slink.c:1188:12: error: ‘tegra_slink_runtime_suspend’ defined but not used [-Werror=unused-function]
   1188 | static int tegra_slink_runtime_suspend(struct device *dev)
        |            ^~~~~~~~~~~~~~~~~~~~~~~~~~~

mark the functions __maybe_unused to make the build happy.

This hits the alpha allmodconfig build (and others).
