| Subject: mips: signal: move sigcontext declarations to header |
| Date: Mon, 4 Dec 2023 12:56:55 +0100 |
| |
| Function declarations should be in a shared header to ensure the |
| prototypes match the definition: |
| |
| arch/mips/kernel/signal.c:439:5: error: no previous prototype for 'setup_sigcontext' [-Werror=missing-prototypes] |
| arch/mips/kernel/signal.c:516:5: error: no previous prototype for 'restore_sigcontext' [-Werror=missing-prototypes] |
