The error is:

Building alpha:allmodconfig ... failed
--------------
Error log:
<stdin>:1517:2: warning: #warning syscall clone3 not implemented [-Wcpp]
drivers/spi/spi-tegra20-slink.c:1197:12: error: 'tegra_slink_runtime_resume' defined but not used [-Werror=unused-function]
 1197 | static int tegra_slink_runtime_resume(struct device *dev)

This was introduced by a bad conflict resolution between the following
two patches.

efafec27c565 spi: Fix tegra20 build with CONFIG_PM=n
2bab94090b01 spi: tegra20-slink: Declare runtime suspend and resume functions conditionally

The fix is at
https://patchwork.kernel.org/project/spi-devel-general/patch/20211013144538.2346533-1-arnd@kernel.org/
and queued in -next.
