To facilitate updating the return type of these functions, remove 'return' before the call to ksft_exit_pass(), as __noreturn prevents the compiler from warning that a caller of ksft_exit_pass() does not return a value because the program will terminate upon calling these functions (which is what the comment alluded to as well).

After commit f7d5bcd35d42 ("selftests: kselftest: Mark functions that
unconditionally call exit() as __noreturn"), ksft_exit_...() functions
are marked as __noreturn, which means the return type should not be
'int' but 'void' because they are not returning anything (and never were
since exit() has always been called).

To facilitate updating the return type of these functions, remove
'return' before the call to ksft_exit_pass(), as __noreturn prevents the

a value because the program will terminate upon calling these functions

SYNC was removed since
aff9da10e21 ("staging/android: make sync_timeline internal to sw_sync")
LKP/0Day will check if all configs listing under selftests are able to
be enabled properly.

For the missing configs, it will report something like:
LKP WARN miss config CONFIG_SYNC= of sync/config

- it's not reasonable to keep the deprecated configs.
- configs under kselftests are recommended by corresponding tests.
So if some configs are missing, it will impact the testing results
