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;
