Having ftrace_write() return -EPERM on failure, as that's what the callers return, then we can clean up the code a bit. That is, instead of: if (ftrace_write(...)) return -EPERM; return 0; or if (ftrace_write(...)) { ret = -EPERM; goto_out; } We can instead have: return ftrace_write(...); or ret = ftrace_write(...); if (ret) goto out; Signed-off-by: NSteven Rostedt <rostedt@goodmis.org>
