From: Linus Torvalds Date: Sat, 18 Sep 2021 17:05:06 +0000 (-0700) Subject: spi: Fix tegra20 build with CONFIG_PM=n X-Git-Tag: v5.15-rc2~19 X-Git-Url: https://repo.jachan.dev/linux.git/commitdiff_plain/efafec27c565 spi: Fix tegra20 build with CONFIG_PM=n 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).
