From e84b354e6ea15ce04b4fe766e75ab1d4379df5c4 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Wed, 24 Apr 2024 10:24:05 -0700 Subject: [PATCH] selftests/ipc: ksft_exit functions do not return 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.
