Subject: [GIT PULL] kcsan: Fix debugfs initcall return type

Hello, Linus,

This pull request provides a fix for a regression introduced in the v5.13
merge window by commit e36299efe7d7 ("kcsan, debugfs: Move debugfs file
creation out of early init").  The regression is not easy to trigger,
requiring a KCSAN build using clang with CONFIG_LTO_CLANG=y.  The fix
simply makes the kcsan_debugfs_init() function's type initcall-compatible.
This fix has been posted to the relevant mailing lists:

https://lore.kernel.org/lkml/20210514140015.2944744-1-arnd@kernel.org/

It has also been exposed to -next testing and has been subject to more
than the usual number of reviews.
