| [ 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). |
