[PATCH 04/16] xtensa: ptrace: add prototypes to <asm/ptrace.h>

From: Randy Dunlap
Date: Wed Sep 20 2023 - 01:21:54 EST


Add prototype for do_syscall_trace_enter() to asm/ptrace.h.
Move prototype for do_syscall_trace_leave() there to be consistent.

Fixes a build warning:

arch/xtensa/kernel/ptrace.c:545:5: warning: no previous prototype for 'do_syscall_trace_enter' [-Wmissing-prototypes]
545 | int do_syscall_trace_enter(struct pt_regs *regs)
