6.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nathan Chancellor <nathan@xxxxxxxxxx>
[ Upstream commit 69e545edbe8b17c26aa06ef7e430d0be7f08d876 ]
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 calls to ksft_exit_...(), as __noreturn prevents the
compiler from warning that a caller of the ksft_exit functions does not
return a value because the program will terminate upon calling these
functions.
